"Sometimes he would be playing a different set of altered changes from those that I'd be playing and neither one of us would be playing the changes to the tune. We would reach a certain spot and if we got there together we'd be lucky. And then Monk would come back in to save everybody. A lot of people used to ask us how we remembered all that stuff but we weren't remembering so much. Just the basic changes and everybody tried anything they wanted to..." description of Monk attributed to John Coltrane.
