"If I could be in any other rock band in the f***ing world," began Dave Grohl, "it would be Thin Lizzy. What a band. We're gonna try something we've never done before and we want to do it for you, special, because we don't do it all the time. Just tonight."

"Jailbreak" was the title track to Thin Lizzy's 1976 album. Considered the group's US breakthrough, it featured their signature song, "The Boys Are Back in Town" alongside "Cowboy Song", "Emerald" and "Running Back", among others. "We just learned that an hour and a half ago," Grohl revealed after the performance.
