Cover: Guns N' Roses - Knockin' on Heaven's Door (1990)
In 1987, Guns N' Roses started including the song in their live sets. A live version of the track was initially released on the Maxi-Single of "Welcome to the Jungle". They recorded a studio version in 1990 for Days of Thunder (soundtrack)'s soundtrack, which was later slightly modified for the 1991 album Use Your Illusion II (basically discarding the responses in the second verse).
Original song: Bob Dylan - Knockin' on Heaven's Door (1973)
Mad World would achieve a second round of success beginning almost twenty years later, after it was covered by Michael Andrews and Gary Jules for the film Donnie Darko (2001). While the Tears for Fears version featured synthesizers and heavy percussion, the Andrews/Jules version was stripped down; instead of a full musical backing, it used only a set of piano chords, a cello, and modest use of a vocoder on the chorus.
"Whiskey in the Jar" is a famous Irish traditional song, set in the southern mountains of Ireland, with specific mention of counties Cork and Kerry, as well as Fenit, a village in county Kerry. It is about a Rapparee (Highwayman), who is betrayed by his wife or lover, and is one of the most widely performed traditional Irish songs. It has been recorded by numerous professional artists since the 1950s. The song first gained wide exposure when the Irish folk band The Dubliners performed it internationally as a signature song, and recorded it on three albums in the 1960s
