“Paulgressive McCartney” - Part 1

Do you agree with me that, since the end of the 60s, Paul McCartney has put some “progressive effort” into some of his songs ? I’m not saying he was a Progressive Rock artist… it’s just that, listening to some of his songs (I’m a Beatlemaniac), I get the impression that he was, in a way, influenced by Progressive bands/artists  or was even trying to sound like them ! I think the Progressive movement was so big and intense by the late 60’s and first half of the 70’s that many bands, playing very different styles, were influenced by Yes, Genesis, Pink Floyd, Gentle Giant, ELP, VDGG, Camel… even listening to bands like ABBA and Bee Gees I sometimes think they borrowed much (or little, whatever…) from those bands I cited… (remember that Lennon was a fan of Genesis !) – SO… what about you, my dear friend ?
