Green Bullfrog was an album resulting from a one-off studio project and recorded between February and May 1970. The album was the idea of producer Derek Lawrence who assembled a group of musicians with whom he had worked in the 1960s. For contractual reasons, the musicians were billed under pseudonyms:

    Albert Lee = Pinta
    Matthew Fisher = Sorry
    Ian Paice, of Deep Purple = Speedy
    Tony Ashton = Bevy
    Rod Alexander = Vicar
    Chas Hodges = Sleepy
    Earl Jordan = Jordan
    Big Jim Sullivan = Boss
    Ritchie Blackmore, of Deep Purple = Boots

Despite rumours at the time Jeff Beck, Roger Glover and Jon Lord do not appear on the sessions. A few originals (penned by Lawrence) were played, as well as many blues-inflected covers of rock songs. The guitar workout song "Bullfrog" is basically Deep Purple's song "Jam Stew" which Purple had originally performed for the BBC Studio Sessions. A record of this session was released in 1972 by Decca in the U.S, as well as a single coupling the tracks My Baby Left Me and Lovin' You Is Good For Me, Baby (Decca 32831.) As a long playing it was first issued on vinyl by MCA Records in the U.K. and Decca records in the U.S.

A reissue was released in 1980 under ECY Street Records on Vinyl in the US.

Four tracks recorded by Green Bullfrog have been published on the Ritchie Blackmore compilation Get Away - Groups and Sessions (2005).

It was remixed at Abbey Road Studios, London in 1991 by Derek Lawrence and released on CD.
