Hawk was very much effected by the changes in the early 1960s - witness, of course, his collaborations with Sonny Rollins (Paul Bley has very funny stories about Sonny, at that session, trying to lose Hawkins, who asked Bley to cue him in) - also, check out Hawk's playing on the Freedom Now/Max Roach sessions, also on the Abbey Lincoln Candid date, in which he does some outside playing - definitely a force to be reckoned with - I've posted this before, but Barry Harris told me that, one night while he was working with Hawkins, Hawkins took a chorus on All The Things You Are that made Barry realize, he said, that he'd spent too much time idolizing Bud and Bird, because here was someone who had survived and kept on going forward -
