I'm a bit concerned that it appears to be an entirely new band under the same name. I'll think about it today and make my final decision tonight. There are a scattering of seats available.
Perhaps the very first Beatles tribute band was the cast of Beatlemania which premiered on Broadway at the Winter Garden Theatre on May 31, 1977 and ran until October 17, 1979 for a total of 1006 performances.
I saw the show in July, 1977. The original cast was...
Mitch Weissman-Paul
Joe Pecorino-John
Leslie Fradkin-George
Justin McNeil-Ringo
It was like going to a Beatles concert!
I saw the show again two years later before it closed. Despite a change in the cast, the experience was still the same. The new cast members were very talented and, again, it was like being at a Beatles concert.
I'm sure you'll find the concert this Saturday quite enjoyable should you go.
