Before I Forget (album): Before I Forget is a 1982 album by Jon Lord, featuring a largely conventional eight-song line-up, no orchestra.

The album also features prolific session drummer (and National Youth Jazz Orchestra alumnus) Simon Phillips, Cozy Powell, Neil Murray, Simon Kirke, Boz Burrell and Mick Ralphs.  Lord used synthesizers more than before, principally to retain an intimacy with the material and to create a jam atmosphere with old friends like Tony Ashton.
