File:A&A 3-7; Austin & Guillermo.jpg

After Ronnie Ramone demands that Ally stop writing songs for Austin, Team Austin auditions a group of replacements, all of which prove to be unsuccessful in the episode "Austin & Alias." The fifth and final potential replacement is a mariachi guitarist who we learn later is named Guillermo. Only Dez finds him remotely acceptable. Swiped from my iTunes copy.
