Guns N' Roses' "Sweet Child O' Mine" was written in just 5 minutes by Slash

The Guns N' Roses mega-hit "Sweet Child O' Mine" was born when guitarist Slash was simply messing around on his guitar and accidentally stumbled on one of rock's most recognisable riffs. The full song came together in just five minutes. The track went on to become one of the band's biggest hits and remains an icon of 1980s rock.
