Gumby is a member of a rock band called The Clayboys. The band has a studio on a farm, where they rehearse. As the band are on their way to their studio, along with Gumby's friends Pokey, Goo, and Prickle, they learn that farmers are about to lose their homes, due to the fact that they cannot pay their debts. The Clayboys decide to hold a benefit concert for these troubled farmers. Unfortunately, the evil Blockheads, the ones who delivered the letters to the farmers, informing them of the bad news, are at the concert. When these two notice Gumby's dog, Lowbelly, crying pearls, they begin to record the music. After the show, the Blockheads kidnap Lowbelly, so they can play the recording they have of The Clayboys' music, and have him cry more pearls so they can get rich! However, they discover that Lowbelly will only cry pearls when he hears the music live, so the two villains now intend to kidnap the band members as well!
