As well as leading his own jazz combos, as a "musicians' musician," Dick Morrissey was in continuous demand as a guest artist with other British or UK-based jazz musicians, most especially with trios and quartets. Thus he was often to be found jamming with established names such as Tubby Hayes, Bill Le Sage, Roy Budd, Ian Hamer, Ian Carr, Tony Lee, Tony Archer, Michael Garrick (who dedicated him his 1965 composition "Leprechaun Leap"), Spike Robinson, Allan Ganley, alto saxophonist Peter King, Ray Warleigh, etc.
