After his drum-dominated instrumental hits "Dance With The Devil" and "The Man In Black", Cozy Powell formed a new band called Cozy Powell's Hammer, whose line-up included Bernie Marsden (later of Whitesnake) and Don Airey (later of Rainbow). The new band's first single and only hit, "Na Na Na" was credited on the record label simply to Cozy Powell, but it's not another drum-dominated instrumental like his other hits, it's an out-and-out rocker that is definitely a worthy addition to any hard rock fan's collection.
