Curious, but very interesting list - could be the first time the words 'Billy Squire' and 'most influential' ever appeared in the same sentence!! - but I personally think if you asked them, I can almost guarantee that many MANY musicians at least starting up back in the 70's and 80's - including many bands/artists on that list - would say that the main reason they first joined a band at all, was due to them either hearing The Beatles for the first time (who aren't on the list) or hearing the Stones (who are)...and wanting to be just like them, so that would be my own answer....pretty much everything goes back to those two really, though btw you also left off The Who, and Bob Dylan, both of whom would for me be right up there just behind the Beatles and Stones in terms of influence, so of the people you did put in the poll, for me, the Stones, though I imagine Zeppelin will get a fair few votes too.
