The origins of Queen lay in the hard rock psychedelic group Smile, which guitarist Brian May and drummer Roger Taylor joined in 1967. Following the departure of Smile’s lead vocalist, Tim Staffell, in 1971, May and Taylor formed a group with Freddie Mercury, the former lead singer for Wreckage.Within a few months, bassist John Deacon joined them, and they began rehearsing.
