OK here are three from me. Still working on my other two choices.
Alan Parsons: I Robot, Classic Records/Arista AL7002 33 rpm (is available as an unreleased Clarity 45 rpm but be prepared to shell out 6 big ones or more!)
Essential Elvis ’57, Analogue Productions APP 057-45 * 45 rpm
Poll Winners Three, Contemporary Records/Analogue Productions S7576 * 45 rpm
