Black Cat Bones issued one album for Decca Records entitled Barbed Wire Sandwich. They replaced their vocalist shortly after releasing the album, adding Peter French to the line-up. Guitarist Rod Price departed soon after to join Foghat and French added his cousin Mick Halls on guitar. Soon after Black Cat Bones changed their name to Leaf Hound.
