Weezerpedia:Today's featured song/October 28, 2008
"Who You Callin' Bitch?" is a song written by Rivers Cuomo intended to be on the scrapped rock opera, Songs from the Black Hole. Before the song was officially released, Rivers was prohibited by Geffen Records from releasing his demos. To loophole this, and allow fans to hear the song, Rivers released the sheet music for the song.
This song is similar to "You Won’t Get With Me Tonight" (which it replaces on Track List 2), though it is much shorter and takes the form of an interlude. Karl Koch described the song as being “slow but huge, rocking.” "Who You Callin' Bitch?" was officially released on Alone: The Home Recordings of Rivers Cuomo.
