[1] Prior to joining OMD, Cooper played the saxophone at some of their concerts, or they used his pre-recorded work.

In 1981, he briefly left OMD to join Dave Hughes for a project called Godot.

His biggest success was "Souvenir", co-written with Paul Humphreys, which reached number 3 in the UK Singles Chart.

After OMD split in 1989, Cooper formed The Listening Pool with ex-OMD members Paul Humphreys and Malcolm Holmes.

Cooper is married to Alexandra Bibby, a classical pianist, and they have two sons, Gabriel and Arthur.
