Cooper had a busy, varied career. In the early 1950s, before he ever heard the words “rock and roll”, he recorded several country 78s. He toured Korea three times as an entertainer for the New Zealand troops. He wrote what is regarded as the first original New Zealand rock and roll song to be recorded, ‘Pie Cart Rock and Roll’.
'Pie Cart Rock And Roll' was used as the name of a 2003 New Zealand compilation, although the compilers revisited the name of the 1957 single slightly as 'Pie Cart Rock'n'Roll'
