The band is most known for its bass player, who was the original bassist of Deep Purple ("Mark 1") from 1968 to 1969 for the first three albums.

The CD reissue on the Angel Air label has six previously unreleased bonus tracks, including a live version of "Ritual" (from the first Warhorse album) and five demos all written by bassist Simper which did not appear on any record before.

Except the song Confident But Wrong being more mainstream rock sounding or the soul based I (Who Have Nothing).

Singer Ashley Holts performance was not praised as he was "tending to hit more annoying high notes".

Back in Time was mentioned for its "unconscious models for the kind of singing" which was parodied by Spinal Tap.
