"October" is the seventh and title track from U2's 1981 album, October. It is a departure from U2's classic sound, as it is a quiet, almost instrumental piece. It was included as a hidden track on The Best of 1980–1990 compilation. It is the only track from October included in the compilation. Lyrics and music "October" reflects the spiritual turmoil of the band at the time it was written, during which three of the band's members were wrestling with whether being members of a rock band was consistent with their Christian beliefs. Lead singer Bono has said of "October": "'October'...it's an image. We've been through the 60s, a time when things were in full bloom. We had fridges and cars, we sent people to the moon and everyone thought how great mankind was. And now, as we go through the 70s and 80s, it's a colder time of the year. It's after the harvest. Trees are stripped bare. You can see things and we finally realize that maybe we aren't so smart after all, now that there's millions of unemployed people, now that we used the technology we've been blessed with to build bombs for war machines, to build rockets, whatever. So 'October' is an ominous word, but it's also quite lyrical." U2 guitarist the Edge plays piano on the track despite having stopped playing piano as a teenager. Author John D. Luerssen describes the piano part as "one of U2's most enduring and meditative keyboard-steered melodies" and considers its somber mood as a reflection of the Edge's recent experience on tour playing in Europe under grey skies. Live performances "October" made its live debut on 16 August 1981 and this performance featured extended, rambling lyrics from Bono that were never used again live. It was a set list staple for much of the October Tour and followed "I Fall Down", another song from the October album that the Edge played on piano. However, it was omitted from the set list at all 1982 dates where U2 supported the J. Geils Band. At the first show of the War Tour's "Pre-Tour", "October" preceded "New Year's Day", a pairing that would later become a famous segue at U2 concerts in the 1980s. The pairing was utilised for all "Pre-Tour" concerts with known set lists, but for the first proper leg and the first two weeks of the second leg, U2 reverted
