This cartoon was first aired as part of episode 41. The gag credit for this episode is: Calor - Body heat.
One of the singers at the audition (and referenced to at the end), 'Wayne Fig Newton', is a nod to famous Vegas singer Wayne Newton. When Brain tells him 'Danke schoen' and Wayne repeats it thoughtfully, it's a nod to his first big hit, "Danke Schoen."
Though not named, the two friends with 'Fred Spinatra' were singers Dean Martin and Sammy Davis Jr, who together with Frank Sinatra and others made up The Rat Pack. Pinky even makes a nod to this by refering to the group of them as 'The Mouse Pack.'
During the auditions, the singer who sings 'What's Up Puppydog' is a parody of Tom Jones, famous Vegas singer well known for the song "What's New Pussycat?"
'Brain's Palace' is a play on world famous Vegas casino and hotel Caesar's Palace.
'Fred Spinatra' is clearly Frank Sinatra, a famous singer who initially made a name for himself singing on the Vegas lounge circuit. A number of his songs are parodied in the episode, as were his nicknames.
