 Gustafson was invited to join them on that basis, but after finding out that Crane retained the rights to the Atomic Rooster name, the quartet decided to continue anyway, but under the name Bullet instead.After recording about half an album's worth of material together, Shaw was dismissed from the lineup and was not replaced with another frontman, his tracks being re-recorded and vocals for remaining tracks being handled by Du Cann and Gustafson, both of whom had served as lead vocalists in their prior bands.Prior to the release of their debut album, they were prompted to change their name yet again, this time to Hard Stuff, due to a legal threat from a US band also called Bullet.
