The third and final verse speaks of a "42-decibel" rock band playing good, loud music in an establishment called "The Shaking Hand".

After the final verse, the song ends with an extended solo by Angus Young, which consists mainly of tremolo picking, string bends, and hammer-ons.

"Let There Be Rock" has been included on four of the band's six official live albums: If You Want Blood You've Got It (sung by Bon Scott, 1978), Live: 2 CD Collector's Edition (sung by Scott's replacement Brian Johnson, 1992), Let There Be Rock: The Movie (Scott, 1979), released in 1997 as part of the Bonfire box set, Stiff Upper Lip Tour Edition (Johnson, 2001), recorded from Plaza De Toros in Madrid from 1996, and Live At River Plate (Johnson, 2012), with the last recorded during AC/DC's Black Ice World Tour at River Plate Stadium in Buenos Aires on 4 December 2009.

Scott was dressed as a priest and the rest of the band as altar boys, with Angus Young wearing a halo prop on his head.

The song specifically mentions Bon Scott, Randy Rhoads, as well as making references to other deceased rock stars such as members of Lynyrd Skynyrd and Phil Lynott of Thin Lizzy fame.
