Rick met my longtime friend Peter Wood (who co-wrote Year Of The Cat) when I brought both in to play on Cyndi's first record.
And we did many things after that that included them both, and they became friends as well, naturally.
Peter played with Pink Floyd for years as the second 'hidden' synth player (when they had the second band up on the wall for example).
so the Roger/Rick connection was thusly made.
