I've posted on this before but it aint here.
Every time i see a tribute Beatles band (meaning dressed up to look like them in whatever period of time) my whole being screams "NNNNNNNNNNNNNNNNOOOOOOOOOOOOOOOO!". I will never go and watch a Beatles tribute band ever. I refused when i was about 12 and nothing has changed in the 20 years or so since.
They don't look like Beatles, they don't sounds like Beatles so get stuffed.
