Better?
It's the first song here that was featured in my initial posting, but Sullivan, Blackmore and Lee play in all songs and are easy to tell apart. Sullivan was Blackmore's guitar teacher.
Albert Lee also played on Jon Lord's Gemini Suite in 1971. Initially another Purple project with an orchestra and performed live a few times, Blackmore did not want to record it for posterity (likely not to confuse the growing Purple audience now used to the In Rock album's - released in 1970 - brand of heavy rock) so at his recommendation Albert Lee stepped in and Gemini Suite became a Jon Lord solo venture.
