They are kind of on a whole new level when it comes Beatles tribute bands.. they probably have a ton more production than the Beatles did - which I could see people complaining about, but they do it really well and it really is a great show.. they have been on The Morning show and gotten national recognition often..
I read an interview with the "John Lennon" dude's guitar tech and he said there are something like 150 different amps modeled for The Lennon and Harrison guys so that the amp the Beatles guys recorded on, is the same amp these guys are modeling so that the sound is perfect - and the Beatles used different amps on every song, so really difficult to get all the right tones etc..
So, quite an elaborate production, but they back it up with excellent musicianship and harmonies etc... If you dig the Beatles, I highly recommend them if they are ever in your neighborhood..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
