younger artists who CAN play their own instruments are of little interest/use to mogols like Simon Cowell etc...
as for The Big Three - yes a far wilder...and at one point far bigger...act in Liverpool than The Beatles were
Johnny Gustafson besides being in a later version of The Pirates (I have that album 'Still Shakin') later played bass for The Mersybeats (for a time) & Roxy Music later on
Decca apparently 'wiped' an entire LP of The Big Three leaving just four songs for an EP release...
