When playing at Uncle Chesko's on the moon Nar Shaddaa, the band was surprised to find their set interrupted by the song stylings of the Yuzzum J'ywz'gnk Kchhllbrxcstk Et'nrmdndlcvtbrx. Impressed, Orbus invited him to join the band, giving him the stage name Joh Yowza.
When Orbus was killed in a firefight with Figrin D'an and the Modal Nodes, the remaining members reformed the group into the Max Rebo Band. The Max Rebo Band later played one of the Wailers' hits, "Jedi Rocks".
