Hebrew phrase meaning "Good luck"
Books with sheet music, usually jazz standard repertoire. Wikipedia sez: "A fake book is a collection of musical lead sheets intended to help a performer quickly learn new songs. Each song in a fake book contains the melody line, basic chords, and lyrics - the minimal information needed by a musician to make an impromptu arrangement of a song, or 'fake it.'"
This might refer to summer events at the Lenox School of Jazz in Lenox, MA, which existed 1957-1960.
From Pynchon's short story The Secret Integration:
- Mr. McAfee was a bass player, but without his instrument. He'd been over in Lenox at some music festival. 
- Pynchon, Thomas, Slow Learner, Jonathan Cape, 1985, p. 170
