I even dispute that . They play almost all their songs exactly the same every time (just playing through the song, or adding in the same traditions), but with KFAD they change up the costumes, stuff said, interaction between the band members, covers sung, different band members joining in singing the "I want you to know" part, sax solos, Billie's various antics, and throw in extra things like the strippers or a Benny Hill scene. It's distinctive so I guess that can make it seem repetitive but really I don't think there's a performance they vary more other than maybe Hitchin a Ride.
