Well if you like jazz and standards (yes I know this is largely a folk and blues forum) and if you have a high speed connection, here's gift for you (and anyone else).
Go here and download The Real Book (in PDF format) as well as the New Real Books (all 3) zipped and in PDF format as well. There's enough sheet music to keep you busy for years, and give you enough material to play piano bars and lounges and then some.
I'd suggest you move fast and grab this stuff. There's no telling how long this page or link will be functional.
