I have about ten fake books, not to mention lots of multiple instances of BIAB tunes. The question is, how do you know version is "correcter"?

To pick just one example ... I was upbraided recently for playing the wrong changes to the bridge of Bernie's Tune. The lead sheet I had used, in Hal Leonard's Ultimate Jazz Fakebook, has formal copyright information, with date and composer, but the guitar player said my chords were wrong.

On the other hand, Real Book 3 has no copyright info on the lead sheet but the chords match what the guitar player insisted were the right ones.

On the other other hand, the lead sheet in Library of Musician's Jazz carries no copyright but the chords match Ultimate Jazz Fakebook. Finally, the chords in Colorado Cookbook match Real Book 3.

I don't want to debate this specific song! I know that a lot of these books were compiled by (semi)casual listeners trying to annotate what they heard, but, short of tracking down the original sheet music for 2500 songs, how does anyone really know which chords are "the real chords" ???
