OK, back to the 70's: Cat Stevens wrote, recorded and released this folk ballad in '70 first as a single and then in "Tea For The Tillerman". Stevens' 1st US hit, peaking at #11. Departing words at the end of 2 yr. romance with young American actress Patti D'Arbanville. The chord progression is taken from a Spanish theme. "...the sadness of leaving and the anticipation of what lies beyond." Covered in '71 by Jose Feliciano and by The Ventures.
Yesterday's answer: "Where Do you Work A-John?" aka "The Delaware-Lackawan Song". This was a staple at the "notorious" Phi Chi Medical Fraternity Wednesday night parties in Philly in the early 70's along with "Roller Derby Queen", "Born to Run", "You Ain't Seen Nothing Yet" and, of course, the one about the Fugawi Tribe. How did we do that and make it to lecture the following morning? YOUTH!
