During that same November, Iain Clark was replaced by Lee Kerslake , once of the Gods. New Zealander Gary Thain , a member of the Keef Hartley Band, joined Uriah Heep as a permanent member in February 1972 halfway through another American tour, replacing Mark Clarke who was exhausted and nearing a mental breakdown. “Gary just had a style about him, it was incredible because every bass player in the world that I’ve ever known has always loved his style, with those melodic bass lines”, Box later said. Thus the “classic” Uriah Heep formed, and according to biographer K. Blows, “Everything just clicked into place.”
