I always saw them as more influenced by the Sex Pistols...or just punk in general. I can easily see Bowie in the production values of them vs. the quick and dirty studio work of mid- 70s punk.

I think Pink Floyd was instrumental in artists going beyond their own boundaries. Full length concept albums, sampling, backmasking, expanding the definition of "radio friendly".

Artistically, I think every musician/ writer is influenceed in some way by everything they listened to, if even in a negative way.

Watching Tommy on vh1classic. That deaf, dumb and blind kid sure plays a mean pinball.
