*Notes
45's and EP's were released worldwide under various labels and jackets
There was an unreleased "Live and Kicking" album recorded and mixed. The tapes are still in Sony's (who bought Columbia) vault.
I've seen the 1971 "P G & E" album referred to as "Hard Burn". I'm still unsure if this album was released under that title overseas.

I asked founding member Brent Block about the "provocative" artwork found on some of the album covers. Here's what he wrote me:
"In all fairness, the first album, "Get It On," was to represent all the various Blues lore. Things such as catching the 4:04 (train), and Long Legged Women. Now, the vibrator? The fact that the woman was completely naked? I can only think these came from someones rather twisted sense of humor.

The "Are You Ready?" album was done by a noted artist (I think his name is signed on the cover), and was in that Pop Art trend. Still, it doesn't take too much imagination to figure out the selection of objects. I can remember not liking a single one of the album covers, including the first Columbia one with the photo of the messy Chelsea Hotel room. I think if you were to ask some of the others, they might cite some artistic reasoning."
