The 15th was a song originally recorded by post punk band Wire in 1979. Electronic duo Ficherspooner did the song justice by re-recording it as a cover on their 2001 debut release. As Wire is relatively unknown beyond the cool kids like myself (Ed. eye roll), many thought that Fischerspooner wrote the song.
Check out the original cover by Wire who were a major influence to many rock and indie bands out there today.
