Answer
Urchin was the name of Adrian Smith's band before he joined Iron Maiden. Formed in 1974, Urchin released two albums, "Urchin" (1978) and "No Turning Back" (1980), before disbanding in 1981. Smith joined Iron Maiden in 1980, replacing Dennis Stratton, and has been a member of the band ever since, contributing to their most successful albums and tours.
