Skip Diamond

Skip Diamond, name-checked on the cover of "Freak Out!" (1966) under the heading "These People Have Contributed Materially In Many Ways To Make Our Music What It Is. Please Do Not Hold It Against Them", was a musician, although probably not too popular. As far as I know, he features as a guest artist on Canned Heat's "Hallelujah" (1969) album, together with... Elliot Ingber (then from Fraternity Of Man).
