Other projects and collaborations

In addition to collaborating with fellow musicians, U2 have worked with several authors. American author William S. Burroughs had a guest appearance in U2's video for " Last Night on Earth " shortly before he died. Video footage of him reading his poem " Thanksgiving Prayer " was used during a Zoo TV Tour television special. Other collaborators include Allen Ginsberg and Salman Rushdie. Lyrics from Rushdie's 1999 book The Ground Beneath Her Feet were adapted by U2 into the song " The Ground Beneath Her Feet ", which was one of three tracks the group contributed to The Million Dollar Hotel movie soundtrack in 2000.
