"Can I Sit Next to You, Girl" is the debut single by Australian hard rock band AC/DC issued on 22 July 1974.
 On August 26, 1974, the song peaked at number 50 on the Aria charts and then disappeared.
 This version has lead vocals performed by Dave Evans prior to his being replaced by Bon Scott, as well as drums by ex-Masters Apprentices member Colin Burgess and bass guitar by ex-The Easybeats member George Young (older brother of band cofounders Malcolm Young & Angus Young; co-producer).
 Originally, AC/DC's first bassist, Larry Van Kriedt, played the bass parts, but George recorded his own over them later.
 In 1975, after Scott joined, the group re-wrote and re-recorded the song as the seventh track on their Australia-only album "T.N.T.", released in December 1975 (see 1975 in music), and as the sixth track on the international version of "High Voltage", released in May 1976.
 The title of this version of the song removed the comma, becoming "Can I Sit Next To You Girl".
AC/DC are an Australian hard rock band formed by guitarist brothers Angus and Malcolm Young in 1973.
 Originally featuring vocalist Dave Evans, bassist Larry Van Kriedt and drummer Colin Burgess, after a number of lineup changes the band settled with Bon Scott on vocals, Mark Evans on bass guitar and Phil Rudd on drums, and released five albums (two limited to Australia) between 1974 and 1977.
 Due to continuing clashes with lead guitarist Angus Young, Evans was later fired from the band shortly after the release of "Let There Be Rock", although "musical differences" was the official reason given for his departure.
 Cliff Williams was brought in as his replacement.
