Joni Mitchell - big name in the 60s folk music movement. Wrote "Clouds" I think...and "here come the clowns" right?? (Older Hobbits would know)
And "Both Sides Now"...that's the only other big hit of hers I can think of off the top of my head.
Heh. Boy do I feel old realizing that it's over 30 years now that I've known that music! I was even listening to the Beatles this morning; now that's almost ancient by today's standards! ;o)
Joni did write "Both Sides Now": "I've looked at clouds from Both Sides Now". "Send in the Clowns" was recorded and made popular by Judy Collins, but I think it was written by Stephen Sondheim.
