From the vaults of the popular psychedelic show 'The Radio Lab' which later became 'Cryptic Propensity Projections' and 'Midnight Collage' on KBOO FM, Portland, Oregon from 1971-1985. (Caution, this program contains explicit sexual content). Bill whips up a spicy stew with The Mothers of Invention and The Firesign Theater. The photo in the video backdrop is Barry Schwam (Schwump) and Bill Reinhardt recording a radio play. KBOO poster with Hound Dog Taylor by Bruce Sorensen. Poster of Bill at the futuristic console in space by Michael Strickland (Sunnyland Band).
