Joh Yowza / Legends J ' ywz ' gnk Kchhllbrxcstk Et ' nrmdndlcvtbrx , more commonly known under his stage name Joh Yowza , was a male Yuzzum performer for the Max Rebo Band , originally hailing from Endor . Biography . Joh Yowza was something of a runt compared to the other taller Yuzzum . When the other members of his herd would look through the Endorian forests for food , he was often left by himself and would sit alone and sing Yuzzum cries . While wandering in the forest for food one day , Yowza found a spaceship that had landed for repairs . He wandered onto the ship , and it was not until later that the captain , Roark Garnet , found him . Garnet nicknamed him " Furball " and kept him on the ship to help with cooking , cleaning , and other tasks . When Garnet ' s ship landed on Nar Shaddaa , Yowza wandered off and found his way into a seedy tapcafe named Uncle Chesko ' s where the band Evar Orbus and His Galactic Jizz - Wailers was performing . Yowza began to sing along right in the middle of the tapcafe , and everyone enjoyed him so much that Orbus decided to make him an official member of the band . Orbus would provide him food and shelter in exchange for Yowza performing in the band . It was his new fellow band - member Sy Snootles who gave him his new stage name of Joh Yowza , which , unlike his real name , was actually pronounceable in Basic , and therefore much better for business . Yowza became somewhat of a celebrity with songs like " Galgamok " and " Jedi Rocks " . When a gig at Chalmun ' s Spaceport Cantina on Tatooine went sour , Evar Orbus was killed , and Max Rebo and Sy Snootles took over the band . They later auditioned for Jabba Desilijic Tiure , and although Bib Fortuna suggested Yowza sit out the first round ( because of a bad experience Jabba had with Yuzzum in the past ) , Yowza later burst onto the stage and joined the band anyway . As it turned out , Jabba was actually quite impressed and rather liked the Yuzzum ' s performance . The band stayed at Jabba ' s Palace for a while . While there , Yowza found a friend in fellow Yuzzum Wam " Blam " Lufba . Though the band accompanied Jabba on his ( ultimately last ) trip to the Pit of Carkoon , they managed to escape the explosion of his sail barge . After this , the group disbanded , and Yowza went to Mos Eisley and found his way onto a small passenger liner . He formed a new band , called the Palpatones , with former Max Rebo Band members Rystáll Sant and Greeata Jendowanian , and agreed to perform on the ship in exchange for a place to stay and the opportunity to travel to exotic locales . And travel he did , along with his friend Wam Lufba , throughout the Outer Rim Territories and the Centrality . Behind the scenes . Joh Yowza was added to the extended musical number in the Special Edition of " " in 1997 . While he was a computer - generated character , another Yuzzum , Wam Lufba , was portrayed as a puppet in the original film and can be seen in the darkened background of the court . Elements of Joh Yowza ' s performance , such as his gravelly , soulful singing voice , and his tendency to play air - guitar while singing , appear to be based on real - world singer Joe Cocker .
