It is possible that he took the name as a stage-name when he started his school band in 1961 called the Rimfires; at this time he played around the Frankston area, an outer suburb of Melbourne, and around the Mornington Peninsula region on the coast.
He also had success as a songwriter with hits written for other artists, including "Rose Coloured Glasses" for John Farnham, "Lady Scorpio" for The Strangers and "Monty and Me" for Zoot.
One of his best-known and most successful compositions, "It's Only a Matter of Time", was the much-played B-side of the single "The Real Thing" by Russell Morris, which was an Australian No.
Short clips of Poulsen performing several songs are included in the documentary Findhorn, produced in 1974 and reissued on DVD by Earthworks Films in 2006.
