The bulk of the album was recorded over two sessions at De Lane Lea Studios, London in 1970, with later string and brass overdubs.

Guitarist Albert Lee had been working with Lawrence as a session player, and the original idea had been to record with former Screaming Lord Sutch bassist Tony Dangerfield.

[1] The backing tracks were recorded in two overnight sessions on 20 April and 23 May 1970 at De Lane Lea Studios, London, starting at 11 pm.

[3] Deep Purple and former Sutch guitarist Ritchie Blackmore had previously worked with Lawrence and brought along their drummer Ian Paice.

[1] Session guitarist Big Jim Sullivan was invited as he had originally taught Blackmore how to play guitar and was greatly admired by him.

[3] The guitar workout instrumental "Bullfrog" is a Deep Purple song "Jam Stew", which had been previously recorded at a BBC Radio 1 session.

It was issued in the UK by MCA Records in March 1972 after Lawrence played some tracks to company president Mike Maitland.

The front cover had a quote from Blackmore taken from an interview with Guitar Player magazine in September 1978, which correctly identified himself, Paice, Lee and Sullivan on the album but mistakenly credited Glover.

The re-release contained extra tracks not on the original release, and additional information and sleeve notes including an interview with Lawrence.

[11] Dave Thompson gave a retrospective review on AllMusic which was mixed, praising the quality of musicians, but felt there was "little [...] to truly engage the attention".
