NellieMay - //Andy, it is not a fact that the Beatles influenced Cohen, Willy Nelson , the GIbbs or Neil Diamond. Sorry, but you are wrong on this. All great songwriters too. And I think McCartney is highly overrated as a songwriter and performer. He needed Lennon. //
I didn't say that they did.
What I said was, their music created a seismic shift in musical and artistic culture around the world. and any popular musician who followed them was indirectly or directly influenced by those changes - and they would all acknowledge that if you ask them. I know, I have asked many of them.
As to your opinion that McCartney is overrated as a songwriter and performer, on that we can agree to differ, no problem at all.
