1976's "Jailbreak" is Thin Lizzy's sixth studio album. This album proved to be Thin Lizzy's commercial breakthrough in the U.S. with the massive singles "Jailbreak" and "The Boys Are Back in Town" (the latter being Thin Lizzy's biggest ever hit). One of the classic rock albums of all time, this deluxe version contains a BBC session from the time as well as previously unreleased tracks.
