In 1998, Matt Loper recorded a techno version of the song.[1] Jono Bacon also recorded a heavy metal version of the song,[2] and the band Fenster recorded a rhythmic version.[3] In addition, there is a Spanish pop punk version recorded by ALEC,[4][5] and a Rick Astley mashup, "Never Gonna Give GNU Up".[6]
A version is used in the free software karaoke video game Sinatra.[7]
The lyrics have been placed in the public domain.[3]
