Les Gilbert (born 10 January 1946 in Melbourne, Australia) is an Australian musician who was a founding member of the 1960s band, Wild Cherries. He appeared on their early recordings, which, together with the band's four singles for Festival, have been picked up for a compilation album by the Half a Cow record company.
In 1990, Gilbert released a "Natural Symphony" CD titled Kakadu Billiabong which is an unedited, high quality recording of dawn at a billabong on Nourlangie Creek in Kakadu National Park in Northern Territory. There is no music overdub and the birds and other animals can be heard going about their morning routine.
