This collection mentions several. I just checked John Szwed's Sun Ra bio, and page 204-205 contains this passage about Gilmore and Blakey:
As some of the musicians began to get a taste of the opportunities New York offered they began to feel restless and ignored. Rehearsals were not enough. John Gilmore spent hours every day practicing, then going out at night to hear lesser saxophonists making money: "I'd been walking around New York and I wasn't working anywhere, and half the cats were out there playing my ideas," he told DownBeat. "I said, 'What is this? Here I am not working, and they're working, and they're stealing my ideas." When Lee Morgan recommended him to Art Blakey as the Jazz Messengers were leaving for a tour of Japan and Europe, he accepted the offer and left the Arkestra. But his bitterness even carried over into the Blakey band, and annoyed Blakey to the point where he let him go:
I criticized him because he'd be talking the way he was thinking. The way he thought about life and what he believed in and why he would put down other people. I didn't think it was right. He was young and running off the top of his head, don't tell me that Lester Young steals from him, or Coltrane steals from him--that's not true. He's off... I wasn't concerned about his playing, he'd be telling me about his fans on Mars or Jupiter, but I said it's the fans on this planet we're concerned with, not back there.
The Blakey quote is from a July 1981 Cadence interview. Szwed doesn't specify when the DownBeat article with the Gilmore quote appeared.
