Can you please tell me the title and artist of the song that was
performed following the atrocities of the 1972 Munich Olympic Games in
which the Israeli athletes were killed by Palestinians?

I seem to recall that it was based on "All the World is a Circle,
sunrise and sundown..."

It was much played on the air at the time here in Australia, but I
haven't heard it in 30 years, and I would like to add it to my
collection.

anubis51,
 
I believe the song you are referring to is "Circle" by Harry Chapin.
The original song is on the album "Sniper & Other Love Songs", which
was released in 1972, and then rereleased in CD format in 2002, due to
popular demand.

Apparently, the late Harry Chapin used to end each concert with the
song "Circle", so you can also find the song sung live on the albums,
"Greatest Stories Live", and according to an Amazon reviewer, on "The
Gold Medal Collection", though it's not listed as one of the tracks.

Reviewer states:
"The collection ends with a poignant live version of his traditional
encore piece, "Circle," with Harry promising to be out to talk to the
fans and to see them again some time soon."
 
 
I hope this answers your question.
