"Sing Along" is a pop song by Swedish singer and composer Per Gessle from his album Party Crasher. It was released as the second single from the album on 4 February 2009 and features two different sleeves, one red and one green.^[1]

An acoustic version of the song was performed live at TV4's breakfast television programme "Nyhetsmorgon" on 6 December 2008. It featured both Per Gessle and Helena Josefsson (vocals), Clarence Öfwerman (piano), Magnus Börjesson (bass) and Jonas Isacsson (acoustic guitar).

When Expressen's Andreas Nunstedt reviewed the Party Crasher album he noted that Helena Josefsson, who sang like a British nightingale from the 1960s on Son Of A Plumber, is prominent. Power ballad à la Joyride».^[2][3]
