Battle of the Bandits - S1.E54

Nimrod's back, this time as a Rock singer in a group called the Slaver Lords. But the Queen catches him, and gives him real Slavers for backup singers. She wants to snare all the humans attending the Battle of the Bands, an interstellar rock contest. Larry steals some of Mogul's henchman to form a band, and the Rangers go: moussed, blow dried, and teased within an inch of their lives.
