Let The Sun Shine In (With The National Urban Coalition, 1970)

I totally missed that this clip has been on Youtube for more than a year now: a 1-minute version of the PSA Aquarius/Let The Sun Shine In, with a National Urban Coalition of 99 other artists and celebrities. There were also 30-second ("Let the Sun Shine In" sung twice) and 2-minute versions (sung 10 times). It looks and sounds awful, but here it is:

Filmed in color in New York on a day in December 1969, first aired during The Ed Sullivan Show of 9 March 1970.

Director Leonard Hirschfield used "a team of seven cinematographers" in the production. There's a 2 minute tape in the collection of the Paley Center (their database mentions Joshua Logan as the director), and another copy in the Historic Films archive (ID COM-19).
