Evar Orbus and His Galactic Jizz-Wailers were a musical group specializing in jizz music. This band was started by Evar Orbus and included notable members such as Max Rebo, Sy Snootles, and Droopy McCool. One of their well-known songs was "(That Joyous Night) I Ate My Mate."
While performing at Uncle Chesko's on the moon of Nar Shaddaa, the band experienced an unexpected interruption to their performance. The Yuzzum musician J'ywz'gnk Kchhllbrxcstk Et'nrmdndlcvtbrx began to sing, catching them off guard. Orbus was so impressed that he asked him to become a member of the band, and gave him the stage name Joh Yowza.
After Orbus was killed during a gunfight with Figrin D'an and the Modal Nodes, the surviving members of the band reorganized and renamed themselves the Max Rebo Band. The Max Rebo Band later performed a rendition of "Jedi Rocks," which was originally one of the Wailers' popular songs.
