Jimi Hendrix, and famous jazz trumpeter Miles Davis, along with drummer Tony Williams, had been trying to enlist the bass guitar duties of Paul McCartney for a recording project in 1969. Validity to this story comes from a telegram that the trio sent to McCartney at the Beatles' Apple Records on October 21, 1969: "We are recording and LP together this weekend in NewYork [sic]," the note starts out according to The Associated Press. "How about coming in to play bass stop call Alvan Douglas 212-5812212. Peace Jimi Hendrix Miles Davis Tony Williams." Alvan Douglas refer to producer Alan Douglas, but his name is misspelled.
Hendrix and Co., got a response from the Beatles camp the following day saying that Paul was on vacation for the next two weeks, and thus unable to participate. Had the session taken place, it would have been quite a unique collaboration with some of the greatest musicians of that era from different genres. The original telegram is part of the Hard Rock Café memorabilia collection, and is on display at the Hard Rock Café in Prague, Czech Republic.
