Sometime during 1984 and/or 1985
A cameo! Jon Lord (together with Eric Clapton, Ray Cooper, George Harrison, Mike Moran, Chris Stainton, Ringo Starr, Jenny Bogle & Anastasia Rodriguez) appeared as part of Billy Connelly's blues band in the final scenes of a film called Water - otherwise featuring Michael Caine. However, this band doesn't appear on the actual soundtrack, at least according to Marc Roberty's book Eric Clapton: the complete recording sessions 1963-1992 (Blandford Press, 1993). In fact, the sound you hear on the film is not the same as that played by Lord & Co. It was dubbed.
