Bob Dylan helped Bono write this song. U2 was touring in Los Angeles on their Joshua Tree tour when Bono woke up with the song in his head ("Lots of songs arrive in a dream state," he said). Thinking it was a Dylan song floating around in there, he drove out to Dylan's place in Malibu and asked if it belonged to him. Dylan told him wasn't, and he helped Bono finish the song. His contribution gave Dylan two writer credits on Rattle And Hum
, since U2 also covered "All Along The Watchtower
" on the album.
