George Hamilton IV did the same with his version of "Don't Let Me Come Home a Stranger" -- that is, dropped the last verse when he recorded it That's a song I wrote with my longtime pal Robin Williams (the folk singer RW, not the other one).

I also heard "Urge for Going" for the first time many years ago when Hamilton sang it in concert. Also the first time I heard Joni Mitchell's name.

And yes, Mitchell recorded "Urge" at least twice. And yes, I agree with the correspondent who loves Dave Van Ronk's reading of the song. Van Ronk was always good with Mitchell material.
