Query: Essential and Convenient ! ! !

If you're a student of Jazz, or a serious Jazz musician, while the REAL BOOK V.1 set the standard for years, V2 is the one that I find REALLY has the best tunes (and even in its bootleg edition was written with much better changes.) - - I host and play up to 300 sessions a year and would go so far as to say that not only does the bulk of my repoitoire come from the REAL BOOK SERIES (1, 2 and 3) but that a very high portion has come from V2, especially considering that until this "legal" edition it was twice as hard to find as the hard to find V1. Trust me on this... If you live in terror of playing or hosting a session and having millions of tunes thrown at you that you don't know, get these three books... In your spare time work on the tunes, and when you're on the bandstand make sure all three are within convenient reach.
