I consider myself somewhat of an expert in the area of Beatles tribute bands, as I've seen so many over the years. 1964: The Tribute sound fantastic, but they've been together for over 30 years (Mark Benson as John is the only original member) and are getting a bit "long in the tooth." Jimmy Pou used to be their George, but now is in a different Beatles tribute band. I know him the best (since 2000) and he's been on a Beatles cruise and ate at our table one night, plus he goes to AROTR as a solo George.
Tom Work is their original George and is now back with them. He looks more like Ron Wood, only older. A new guy, Mac Ruffing, is now Paul, but he is a bit younger than the others, is good looking, and plays left-handed. You won't be disappointed as technically they are very good. Just overlook their age if you can. I just saw them in Atlanta last Sept. for about the 5th time.
The Return (formerly The Roaches) is a Georgia group and are younger (mid to late 30's) and are very good. Michael Fulop (George) was 17 when I first met him in 1995! He's the only original member. Have seen them about 10 times .
But the best of them all, "without a shadow of a doubt" is The Fab Four! They are in their late 30's or so and look and sound fantastic! Their attention to detail is incredible. First saw them in 2011 in Liverpool during Beatles week and was blown away! Gavin Pring (George) is actually from Liverpool (Bootle) and the other guys are from CA. Ardy Sarraf (Paul) taught himself to play left-handed bass and acoustic (for Yesterday) as he's naturally right-handed. Saw them again in Atlanta (front row on the "Paul" side) What a blast! And am going to see them at Atlanta Symphony Hall May 8th! Try to catch them on a PBS membership drive special and you will see what I mean.
