January, 1970 - release date for fist album according to reissue liner notes (possibly referring to second pressing).
May, 1970 - release date for second album according to the official site less support for this more likely the date of recording or cutting (or both I don't know if there is a difference).

February, 1971 - release date for second album according to reissue liner notes much more support for this.

October, 1971 - release date for The Best Of ... Featuring The Penguin according to the official site I have no contradicting dates as it has unfortunately never been reissued.
October, 1971 - release date of third LP according to liner notes. Mistake could be caused by the above compilation (catalogue number implies it came first). This could also be the cut date but the compilation also being released seems too coincidental.
