Now, solve this: "One" is a song by Irish rock band U2. It is the third track from their 1991 album "Achtung Baby", and it was released as the record's third single in February 1992. During the album's recording sessions at Hansa Studios in Berlin, conflict arose between the band members over the direction of U2's sound and the quality of their material. Tensions almost prompted the band to break up until they achieved a breakthrough with the improvisation of "One"; the song was written after the band members were inspired by a chord progression that guitarist the Edge was playing in the studio. The lyrics, written by lead singer Bono, were inspired by the band members' fractured relationships and the German reunification. Although the lyrics ostensibly describe "disunity", they have been interpreted in other ways. Question: Who wrote the lyrics to the emblematic song recounted through the replaying of old recording tapes in the film From the Sky Down? Answer: Bono
Solution:
One is a song by Irish rock band U2.
