People involved
Graham Bonnet (vcl), together with: Russ Ballard (gtr); Andy Bown (kbr); Mel Collins (sxp); John Cook (kbr); Martin Ditchman (prc); Kirby (gtr); Adrian Lee (snt); Jon Lord (kbr); Mick Moody (gtr); Neil Murray (bss); Ian Lynn (kbr); Richard Parfitt (gtr); Cozy Powell (drm); Francis Rossi (str/snt); Chrissie Stewart (bss); Gary Twigg (bss).
According to the album sleeve notes, Lord only guests on one of the album tracks, viz. "Don't Stand In The Open". The sleeve notes on the Liar-single credits Lord for keyboards; he does not, however, appear on the track "Liar". The b side - i.e. "Bad Days Are Gone" - doesn't appear on the album so Lord could be on that.
