Although the great Thin Lizzy was responsible for countless all-time classic hard rock tunes, undoubtedly their best-known Lizzy track is "The Boys Are Back in Town." A permanent fixture on classic rock radio the world over, the song contains all of the band's musical trademarks -- Phil Lynott's poetic (yet tough) storytelling lyrics, Scott Gorham and Brian Robertson's melodic guitar harmonies, etc. Before the release of Lizzy's 1976 release Jailbreak, the band had yet to truly break through worldwide, despite racking up a Euro-hit in the early '70s with a cover of "Whiskey in the Jar." But "The Boys Are Back in Town" changed all of that. The original title for the song was "G.I. Joe Is Back in Town," due to Lynott's admiration of the popular U.S. comic book/action figure G.I. Joe, as the lyric's dealt with a Vietnam soldier coming back from the war. According to the book Phil Lynott: The Rocker (by Mark Putterford), the main melodic guitar riff was based on the early Bruce Springsteen song "Kitty's Back" (from 1973's The Wild, the Innocent and the E-Street Shuffle). After unsuccessfully nailing the lyrics with the "Vietnam soldier" theme, Lynott changed the lyrics to a bunch of rowdy friends going out and having a good time. When the single was issued in April of 1976, it was an instant hit, reaching number eight in the U.K., topping the charts in Ireland (Lynott's home country), and climbing to number 12 in the U.S. The song has proven to be timeless, as it has become a staple at sporting events, as well as being used in T.V. commercials and in the children's movie Toy Story.
