"Get It On" is a song by the English rock band T. Rex, featured on their 1971 album Electric Warrior.

In the United States, it was retitled "Bang a Gong (Get It On)" to avoid confusion with a song of the same name by the group Chase.

While in New York in March 1971, Bolan asked drummer Bill Legend to help him brainstorm drum patterns for a song idea that would later become "Get It On".

[9] Wakeman, who was desperate for work at the time to pay his rent, had bumped into Bolan in Oxford Street, who offered him the session.

[14][15] During a December 1971 Top of the Pops performance, Elton John mimed playing a piano on the song.

The track was a strong hit on the US Billboard Hot 100 chart, where the single peaked at number nine (one place higher than the original) in the summer of 1985.

[37] The song also was performed live with Michael Des Barres on vocals, in the Miami Vice episode "Whatever Works",[38] which featured all of the then-touring group in cameo roles.

[47] English rock band Def Leppard named their twelfth studio album, Diamond Star Halos, after a line in the song.
