John Du Cann

John William Cann (5 June 1946 – 21 September 2011), later known by his stage name John Du Cann, was an English guitarist primarily known through his work in the 1970s band Atomic Rooster. His early bands included the Wiltshire-based The Sonics (not to be confused with the 1960s US band of the same name) and London-based The Attack, which released "Hi Ho Silver Lining" a few days prior to Jeff Beck. He went on to lead a psychedelic, progressive, hard rock band called Andromeda, before being asked to join Atomic Rooster, featuring re-recorded guitar parts and vocals for their 1970 self-titled debut album, and the albums Death Walks Behind You (1970) and In Hearing of Atomic Rooster (1971).

Upon departing Atomic Rooster in 1971 he formed Daemon, later renamed Bullet, then Hard Stuff, releasing two albums based more heavily on aggressive guitar work. In 1974 he was a temporary guitarist in Thin Lizzy for a tour of Germany. Sometime following this, his manager suggested a name change for him from John Cann to John Du Cann.
