I don't know how Maureen McGovern got associated with
One Tin Soldier, but the artist who covered the song in the 1971 film is Coven.
I looked on the
Billy Jack Soundtrack liner notes that I found online.
Even Coven's version is a cover. The song was originally recorded in 1969 by The Caste. The song is written by two Candians. (Pacifist Canadians, what??

)
I'm probably the one who associated Maureen McGovern with the song when I put
One Tin Soldier into YouTube and her track came and I just made an assumption. My bad.

Proper credit goes to Coven for covering the song on the
Billy Jack Soundtrack.
