I think I already have every jazz standard in 3 or 4 versions.

You just need to get creative on the net and find some of the 10,000 or so available tunes in Band in a Box format.

Another way is if you can play from a fake book with chords look for the Montooth books of Standards. I have all of those.

And the backing tracks from Notes Norton without the melodies. The books are cheapest at Amazon, order like 3 and get free next day delivery, and you can order the songs with both sets of chords, the regular and the substitute chords in red by Frank Montooth, and download them.

More than one way to skin thi s c a t.
