Not Steve Miller... but Jimi. Here is part of the story:
Little Richard - 'I fired Jimi, who was using the name Maurice James all the time I knew him. He was a damn good guitar player, but the guy was never on time. He was always late for the bus, and flirting with the girls, stuff like that. It came to a head in New York, where we had been playing the Apollo, and Hendrix missed the bus for Washington, DC. I finally got Richard to cut him loose. So when Hendrix called us in Washington, D.C., I gave him the word that his services were no longer required. We had some words. I explained why we were doing this. I was running the road for Richard, and I didn't accept that kind of bull####'.
