Strange views of Coltrane, who was a modest and deeply serious chap (not in the Bonj sense), and the absolute opposite of a show-off. Jelly-Roll Morton, Stan Getz -they were show-offs, but that's fair enough when you're that good. And only on an internet forum could anyone get away with a statement as preposterously cavalier as "Davis was a bit patchy IMO", about one of the most important and influential musicians of the century.
Yep go and see Rollins if you can - he's in his late seventies now and it's showing, but there's only one of him. He has a voice a bit like Kermit the frog.
