I'm transferring this question from the Tom Rush thread. Does anyone besides me remember hearing a recording of Joni Mitchell singing Urge for Going? I know I heard it once on a radio station in Philly in 1970, and am fairly sure I heard it on a restaurant juke box in Princeton in 1971, which would indicate it was released as a 45. (For those GenXers out there, that's like a CD single, but larger.) Any help?

Aloha,
Mark
