Well, they say the man who knew the names of all the tunes didn't know the tunes.

If you've been listeninmg to any tune sessions you'll probably know lots of the tunes anyhow. You pick them up by a process of osmosis.

Any set of tunes in most sessions seems to end with someone saying. "What was that we were playing?", followed by an argument as to what it was. The best musician in sessions I klnw when you ask him he's likely to say "it was e minor and D wasn't it?" or whatever.
