What is the name of the rock star who is Judy Jetson's crush?

Jet Screamer is the rock star who becomes Judy Jetson’s crush. He appears in the original-series episode “A Date with Jet Screamer,” where Judy’s enthusiasm for the fashionable singer drives the episode’s romantic and musical plot.

Judy wins a date with Jet as the grand prize in a songwriting contest. George secretly tries to sabotage her entry by replacing her song with Elroy’s coded message, but the plan fails and Judy still wins. George accompanies her because he distrusts Jet and wants to stop the date. His opposition eventually turns comic when he ends up playing drums during Jet’s performance and begins enjoying the music himself.

Jet Screamer is not the same character as a generic “rock star,” nor is he related to Zapp Brannigan or Johnny Bravo. The episode is notable because it places Judy’s teenage interests at the center of the story and shows the series borrowing from early-1960s pop-star culture.
