Levi Smith's Clefs, originally The Clefs, were an Australian R&B, pop rock group, which formed in Adelaide in 1963. Lead vocalist, Barrie "The Bear" McAskill, joined in 1965. In 1967 he took over and renamed the group after founding keyboardist, Winston "Tweed" Harris, left. They released a sole studio album, Empty Monkey, in March 1970 and underwent numerous line-up changes until they disbanded in 1972. After their time in the band various members formed the groups: Tully, Fraternity and Southern Contemporary Rock Assembly (SCRA). Winston Harris (1941–2004) died of throat cancer, aged 63. A drummer from 1970 to 1971, Russell Dunlop (1945–2009), died after a seizure, aged 63. Richard Lockwood, flautist and saxophonist in 1968, died in 2012 of bowel cancer.
