David Coverdale to replace Ian Gillan. Coverdale had fronted a local group called The Government, which had played with Deep Purple on the same bill in 1969, so he and the band were familiar with one another, and after sending a tape and later auditioning, Coverdale was admitted into the band, with bassist Glenn Hughes adding his own vocals as well. In February 1974, Deep Purple released their first album with Coverdale and Hughes titled "Burn" which was certified Gold in the US on 20 March 1974 and in the UK on 1 July. In April 1974, Coverdale and Deep Purple performed
