Fans of 70's sitcoms know dearly departed Sherman Hemsley as the irascible, forever-irritated star of the beloved and long-running All in the Family spin-off, The Jeffersons. According to this incredible article at Bad Ass Digest, though, he was also a huge fan of some of the most obscure progressive rock acts of the era who cut an (as yet unreleased) album with Yes front-man Jon Anderson and paid for Gong leader Daevid Allen's Jamaican honeymoon. Oh, and he ran an LSD lab and crack cocaine kitchen out of his Hollywood home. There's more, including links to videos of some of Sherman's all-time favorite prog tunes, at the link. So check it out.
