If you've ever sat down for a PBS pledge drive, chances are you've seen them. Those towering stone backdrops, the mist, the kilts, and that wall of vocal harmony that hits like a physical force. It’s Celtic Thunder. But if you haven’t checked in for a few years, looking at the stage can feel a bit like trying to solve a puzzle. Faces change. Guys leave to pursue solo careers, some come back after years away, and tragically, one of the most beloved voices was lost forever.
The question of who counts as Celtic Thunder band members is actually trickier than it looks. It’s not like a standard rock band where the four guys you see on the first album are the same four guys thirty years later. It’s more of an ensemble—a brotherhood with a revolving door that keeps the sound fresh while staying anchored in that massive "Heartland" sound.
The 2026 Core: Who is Touring Right Now?
As of early 2026, the lineup has solidified into a powerhouse quartet for the "An Intimate Evening with Celtic Thunder" tour. This is a bit of a "dream team" for long-time fans.
Basically, the current touring roster features Emmet Cahill, Damian McGinty, Neil Byrne, and Ronan Scolard.
It’s a fascinating mix of the old guard and the new blood. Damian McGinty is the guy everyone remembers as the "kid." He was only 14 when this whole thing started back in 2007. He left for a while—you might remember he won The Glee Project and landed a role on Glee—but he’s been back in the fold for years now, bringing a much deeper, more mature baritone to the group. Honestly, seeing him stand next to the "new" guys makes you realize just how long this group has been a part of the cultural landscape.
Then there’s Neil Byrne. If Damian is the heart, Neil is kinda the glue. He started out as a backup musician for the group before stepping into a lead role. He has that easy, folk-singer vibe that balances out the more "theatrical" tenors.

The Return of Emmet Cahill
For many, Emmet Cahill is the voice of Celtic Thunder. He’s a world-class tenor who has spent plenty of time touring the US as a solo artist, selling out Carnegie Hall and hitting number one on the Billboard World Music charts. Having him back in the lineup for 2026 is a massive deal for the fans who missed that soaring, operatic quality he brings to tracks like "Danny Boy."
The Multi-Talented Ronan Scolard
Ronan Scolard is the newest "permanent" fixture in this group of Celtic Thunder band members. He isn't just a singer; he’s a musician’s musician. He often handles musical direction and brings a contemporary edge to the arrangements. His presence allows the group to lean into more complex, layered harmonies that keep them from sounding like a tribute act to themselves.
The Original Five and the George Donaldson Legacy
You can't talk about this group without looking back at the 2007 originals. The vision of producer Sharon Browne and musical director Phil Coulter was to find five distinct personalities.
The "Original Five" were:
- Damian McGinty (The young one)
- Keith Harkin (The blond surfer-vocalist)
- Ryan Kelly (The "dark" and theatrical one)
- Paul Byrom (The classical tenor)
- George Donaldson (The Scotsman and the ballad singer)
George Donaldson's story is the one that still brings a tear to the eye of the "Thunder Heads" (the nickname for the die-hard fans). He was the "Big George" of the group—the oldest, the most grounded, and the only one from Scotland. He was a bus builder by trade before the show made him a star. Tragically, George passed away in 2014 from a sudden heart attack at his home in Glasgow.

The group has never truly "replaced" him. Instead, they’ve honored him. Even in the 2026 shows, his influence is felt in the way they approach the big Irish and Scottish ballads. They often include tributes to him in their setlists, acknowledging that he was the "steadfast" one who held the younger guys together in the early years.
Why Do the Members Keep Changing?
It’s a fair question. Why isn't Ryan Kelly touring this year? Where did Keith Harkin go?
The reality is that being one of the Celtic Thunder band members is an exhausting gig. We’re talking about months-long bus tours across North America, Australia, and Europe. Ryan Kelly, for instance, has been a staple for nearly two decades, but he also has a massive solo following and a successful duo project with Neil Byrne called Byrne and Kelly. Sometimes these guys just need to step away to breathe, record their own music, or be with their families in Ireland.
Keith Harkin is another example. He was the resident heartthrob for years, but he eventually pivoted to a full-time solo career and his own touring company. The "brand" of Celtic Thunder is designed to survive these exits. It’s built on the songs and the arrangements rather than just one person.
A Quick List of Past Principal Singers
- Paul Byrom: The first to leave (2010) to pursue his solo career in the US.
- Emmett O'Hanlon: An Irish-American baritone who joined in 2014 and brought a very "New York" energy to the stage.
- Michael O'Dwyer: A soulful singer who stepped in during the 10th-anniversary era.
- Colm Keegan: A fan favorite with a teaching background who left to focus on his "C學院" (Colm Keegan Academy) and his family.
The "Thunder Band": The Unsung Heroes
People usually focus on the singers, but the actual band—the guys playing the instruments—are just as much "members" as the guys at the front of the stage.

They aren't just session players. These are world-class musicians who have been with the production for years. David Munro, for example, has been the long-time musical director and the guy behind the piano, shaping the "Thunder" sound. You've also got incredible fiddlers, pipers, and drummers who have to stay perfectly in sync with the massive orchestral tracks playing in the background. Without the "Thunder Band," the singers would just be five guys doing karaoke.
What to Expect Next
If you’re planning on seeing them live or picking up the latest DVD, here is what you need to know about the current state of the group:
- The Sound is More Intimate: The 2026 tour is moving away from the "massive theatrical production" style and toward a more personal, storytelling vibe.
- Solo Spots Still Rule: Even though it’s an ensemble, the show is still structured to give Emmet, Damian, Neil, and Ronan their own time in the spotlight.
- The Catalog is Huge: They have 15+ years of music to pull from, so expect a mix of the old standards like "Ireland's Call" and "The Wellerman" along with brand-new arrangements.
Honestly, the best way to keep up with who is "in" or "out" is to follow their official tour announcements. They are very transparent about the cast for each specific tour.
If you want to dive deeper into their history, the best place to start is the Heritage or Legacy albums. Those collections really highlight how the different voices have blended over the years, regardless of who was standing on the stage at the time. Keep an eye on their 2026 Australian and North American dates—this particular quartet of Emmet, Damian, Neil, and Ronan is being hailed as one of their strongest vocal lineups in a decade.
For fans who want to support the individuals, checking out the solo albums by Ryan Kelly or Keith Harkin is a great way to see what the "alumni" are up to these days. Their solo work often takes a much more "raw" folk approach than the big, polished Celtic Thunder productions.
