Bootleg is a double live album by American hard rock band Aerosmith, released in October 1978.

During their 1978 tour, several of the band's concerts were professionally recorded by producer Jack Douglas for radio broadcast, and subsequently bootlegged.

"[2] In an effort to combat the illegal records, the band's management asked Douglas to compile the double live album.

In addition to previously unrecorded covers "I Ain't Got You" and "Mother Popcorn", the album also features a version of "Train Kept A-Rollin'" which inserts an uncredited "Strangers in the Night".

The back of the CD cover includes two coffee stains over the picture of Joe Perry playing before a live audience.

"[6] In his own 2014 memoir Rocks, Perry said that the idea behind the LP confounded their label Columbia: "We were working on Live!

Bootleg starts with "Back In The Saddle", that whole intro with the crowd going crazy and the flash-pots going off, that whole build-up, made it so exciting to me.
