Show of Hands (American eclectic or jazz-rock)

Show of Hands was little-known American jazzy progressive/psychedelic rock trio which was formed in 1967 and disbanded in 1972.
They recorded only one album called "Formerly Anthrax" in 1970. Their music is usually described as jazz-rock with dominating organ playing, however I suppose Eclectic Prog would be the best place for them.

Most interesting parts of their sole album is almost 7 minutes instrumental "I Want to Fly" and "No Opportunity Necessary, No Experience Needed" which is cover of Yes songs from thier second album.

line-up:

Jerry McCann (vocals, guitar, flute), Jack Jacobsen (Hammond organ, piano), Rick Cutler (drums, percussion)
