The Mutton Birds were a New Zealand rock music group formed in Auckland in 1991 by Ross Burge, David Long and Don McGlashan, with Alan Gregg joining a year later. Four of their albums reached the top 10 on the New Zealand Albums Chart, The Mutton Birds, Salty, Envy of Angels and Rain, Steam and Speed. They had a number-one hit with "The Heater", while their two other top 10 singles were a cover of "Nature" by the Fourmyula, and an original, "Anchor Me". From 1996 to 2000 the group were based in England; they returned to New Zealand and then disbanded in 2002.
