paul may have had more dealings with jimi.paul was a big part of organizing the monterey pop festival.and was on the board of directors.he had hendrix booked.read about the fest here...http://en.wikipedia.org/wiki/Monterey_Pop_Festival
the beatles were slated to play at one time and all worked for thr festival..they did posters...one shown here...http://home.earthlink.net/~rwm/beatles1.html
the others were kinda not hip to playing it i read,but paul was wanting it bad.he worked on other posters by himself...there is some on line some place maybe he did this one....
for some reason they didn't play the festival but went there i think this picture here is them in the audience minus paul plus yoko....http://originalonefeather.tripod.com/id6.html

The link to that photo is not them at Monterey. I think it's the '69 Isle of Wight. John and George didn't have full beards and shoulder length hair in '67. I don't think any of them went to Monterey actually.
