Glam Slam '91 is a track premiered on Twin Cities public radio station WLOL on 6 January 1991. It was sent to them to promote Prince's newly opened Glam Slam club in Minneapolis, and was played on the station several times that day.
While it shares its title with the 1988 song Glam Slam, it can hardly be considered a revised version of that. Instead Glam Slam '91, forecasts Gett Off with its 'Everybody grab a body, pump it like you want somebody/wanna party' chorus and large parts of the rest of the lyrics to that song used.
Musically it mostly uses samples and parts from Love Machine, first recorded in the summer of 1989, including parts that did not end up on the released version of that. It also uses a sample from Madhouse's Twelve, while its sung 'Glam Slam' chorus is lifted from Escape.
