"Fat Boy" (1990)
“Fat Boy” is a working title of a song developed for Achtung Baby. “Fat Boy” was an early version of “Until the End of the World”.
The Edge discussed the track in U2 by U2:
‘Until the End of the World’ was built around a Bono guitar riff from ‘Fat Boy’, an idead from one of our brainstorming sessions in STS. These demos later became the Berlin Bootleg when a tape fell into the wrong hands and ended up all over the world. It didn’t seem to be going anywhere but I loved the riff. We met German film-maker Wim Wenders in Berlin when he shot a video for our cover version of Cole Porter’s ‘Night and Day’, recorded for the Red, Hot and Blue AIDS charity album. Wim was working on a movie called Until the End of the World and he was looking for music. Back in Dublin I got something going using the Fat Boy riff and cut a backing track with Adam and Larry. Bono started working up ideas and it was so exciting that I said, “You know what, we have to put this on our record.’ So we told Wim, “You can have it but we want it too.’ He was cool with that. Then we said, ‘By the way we’re borrowing your title.”
