Joh Yowza

Joh Yowza functioned as a male Yuzzum entertainer within the Max Rebo Band. Yowza became a member alongside existing band members Maximilian Rebo, Sy Snootles, and Droopy McCool, who had already been performing together for a number of years. He frequently sang duets with Snootles, who served as the principal singer. Rebo found Yowza annoying and disliked his tendency to dominate the stage. Yowza also had his own original musical works that he insisted on playing despite the band's planned setlist, which Rebo also disapproved of.

In the time leading up to the Battle of Endor, Yowza and the other band members played at Jabba the Hutt's palace located on the planet Tatooine. The performance was interrupted when Jabba threw his slave dancer Oola into the rancor pit, causing Yowza to gasp in shock. Among Jabba's entourage, many individuals despised Yowza's singing and wished to silence him permanently. The Hutt, however, seemed to enjoy the Yuzzum singer, and his opinion was the only one that mattered within the palace. At some point, Yowza departed from the band and was scheduled to perform a solo show at Oga's Cantina on Batuu a few rotations following the skirmish at Kat Saka's farm.
