On a lot of the old music sheets there are chords that are automatically changed on sight. ie: Dmin6 to E7 is played Bmin7b5 to E7. In many cases a Cmaj7 to Cmin is played Cmaj7 to F13+11. On my trio gigs if I work with a new bassist I have chord sheets written out so we will be on the same page. Mac is right about the old jam sessions. You had better know the tune if you want to sit in. Back in the day I've seen quite a few players who were asked to get off the stage and not so politely either. Depending on who I'm playing with determines whether I can play sub chords or stick close to the original chords. Listen to Tony Bennett's accompanists. They're not playing "fake book chords". I'm only writing this in regard to jazz players. This doesn't apply to other genres (pop, rock). I also work with some very good vocalists and all of them like good chords as opposed to sheet music chords. As I posted earlier, I get a lot of the good chords from recordings of the heavys.
