This is not the best U2 single available from the 'Pop' releases.
"Last Night on Earth" [Single Version]. Compared to the version on 'Pop', this single version has an abbreviated intro, added vocals in the middle section, and louder guitars in the chorus.
"Pop Muzik" [Pop Mart Mix]. The first 4:30 of the instrumental track were used in the opening sequence of the Pop Mart tour, but in this version, Bono "sings". However, the last 4:00 minutes have no purpose at all.
"Happiness is a Warm Gun" [The Gun Mix]. This is an interesting cover of the Beatles classic, originally recorded for an ill-fated TV show. However, for those who were not enthralled with some of the more overworked material on 'Pop', this will be a disappointment.
