It is in the third and final part where a sort of James Bond kind of parody ends up at Duff Stadium where Steely Dan is playing.
Donald Fagen voices his own appearance consisting of one line: "Drugs at a Steely Dan concert? I never thought I'd see the day."
Then our agent heroes have to fight their way through an, as Homer puts it, "army of jazz rock afficiaondos aged fifty and up" while the intro to Babylon Sisters is playing.
Homer first ordered the band to play Deacon Blues, then Royal Scam, before deciding on Babylon Sisters.
The interior of Duff Stadium in Springfeld looks somewhat inspred by the Beacon Theatre, New York, where the non-cartoon version of Steely Dan is playing a series of shows October 12 - 29.
