Gary T, I think "Big Yellow Taxi" might be right, because I remember Ladies of the Canyon came out in 1970 or 71 (my freshman year) and that's when I remember hearing the single of "Urge for Going" on the jukebox. Sounds like I really oughta get that CD. A few weeks ago while driving to the other side of the island I surprised myself by singing almost the whole "Clouds" album from memory. Maybe that's why my memory seems to be failing so often these days -- it's full of Joni Mitchell songs!

Aloha,
Mark
