one recurring theme in the Kelley book that I'm skeptical about is that Monk, contrary to myth, was utterly reliable for gigs - and I just found this little quote from Teddy Charles on Marc Myers' Jazz Wax site, about the 52nd Street scene in the 1940s on Coleman Hawkins' gig:
"I knew Hank Jones, who was often in the club with another band. One time when Monk didn't arrive by show time, Hank told me to go up and play. So I did. I was fearless then. I sat down and played behind Coleman Hawkins until Monk walked in. Then I’d clear out. After that I sat in regularly until Monk arrived."
hmmmmm....sounds like a fairly regular thing -
