The Runner Beans
From the movie Privilege (1967). Unnamed in the film, their name is given in the credits as "The Runner Beans" and credited as The George Bean Group. On the soundtrack album, they are credited as George Bean and the Runner Beans.
This band of surly-looking musicians rock out on "Onward Christian Soldiers" as part of the state's scheme to turn their manufactured pop idol protagonist Steven Shorter from bad boy to redeemed conformer. A batch of padres is asked "Is it a hit? Or a miss?" - a reference to then current BBC show Jukebox Jury.
The band opens Shorter's big gig with that "And Did Those Feet in Ancient Time" hymn to kick off the start of Christian Crusade Week.
