Sons of the Vegetal Mother (also known as The Vegetals to fans) were an Australian "esoteric special-occasion progressive band", formed in late 1969, with a floating line-up based around the nucleus of Ross Wilson and Ross Hannaford. A side-project of the band, formed in 1970 was Daddy Cool, which played 1950s doo-wop music plus some originals. Daddy Cool were to eclipse their parent band when their debut single "Eagle Rock" reached No. 1 on the Australian National charts.
