Which Scottish singer had the surname Leitch?

Donovan Philips Leitch (born 10 May 1946), known as Donovan, is a Scottish singer, songwriter and guitarist. He developed an eclectic and distinctive style that blended folk, jazz, pop, psychedelia, and world music (notably calypso). He has lived in Scotland, Hertfordshire (England), London and California, and, since at least 2008, in County Cork, Ireland, with his family. Emerging from the British folk scene, Donovan reached fame in the United Kingdom in early 1965 with live performances on the pop TV series Ready Steady Go!.

His most successful singles were the early UK hits "Catch the Wind", "Colours" and "Universal Soldier" in 1965. In September 1966 "Sunshine Superman" topped America's Billboard Hot 100 chart for one week and went to number two in Britain, followed by "Mellow Yellow" at US No.2 in December 1966, then 1968's "Hurdy Gurdy Man" in the Top 5 in both countries, then "Atlantis", which reached US No.7 in May 1969.
