Does anybody know where I can get realbooks volumes 1,2, and 3 for bass clef? It seems as though when the Hal Lenard 6th edition came out the other ones went out of circulation. I'm not looking for the 6th edition as song keys, melodies, chords, and many other things don't line up when playing with most musicians (who use the other book). Anybody know? The books on CD format would be just as good.
