5.15 by The Who

"5:15" (sometimes written "5.15" or "5'15") is a song written by Pete Townshend of British rock band The Who. Part of the band's second rock opera, Quadrophenia (1973), the song was also released as a single and reached No. 20 on the UK Singles Chart, while the 1979 re-release (accompanying the film and soundtrack album) reached No. 45 on the Billboard Hot 100. Although written as "5.15" on the single covers in some countries, on the back cover of Quadrophenia (the album from which the song is taken) it is written as "5:15", and some single covers also have "5:15".
