I've been thinking, if an Electric Mayhem song where Dr. Teeth was not the lead singer was released on an album, how would the performers of the song be listed? If any Electric Mayhem song led by Floyd was released (I know, Mr. Bassman and New York State of Mind were, but he's the only member who got vocals on those songs), or if Rockin' Robin was released, it would be weird to list the performers of the songs as "Dr. Teeth and the Electric Mayhem", and it would sound a little odd if it listed the singers as "Floyd and the Electric Mayhem" or "Janice and the Electric Mayhem" (maybe if they said "with" instead of "and", though it'd still be odd considering they are part of The Electric Mayhem). Would it just say "Electric Mayhem"? In the case of Rockin' Robin, it could just list Janice as the singer, or maybe "Janice with Dr. Teeth, Animal, and the birds".
Maybe that's why those songs were never released on any albums (though no tracks from the last season have been released on any albums).
