The members of U2 have commenced a number of side projects, sometimes in collaboration with some of their bandmates. In 1985, Bono recorded the song "In a Lifetime" with the Irish band Clannad. The Edge recorded a solo soundtrack album for the film Captive in 1986, which included a vocal performance by Sinéad O'Connor that predates her own debut album by a year. Bono and The Edge wrote the song "She's A Mystery To Me" for Roy Orbison, which was quality on his 1989 album Mystery Girl. In 1990, Larry Mullen co-wrote and produced a song for the Irish International soccer team in Italia '90, called "Put 'Em Under Pressure", which toped the Irish charts. Together with The Edge, Bono wrote the song "Goldeneye" for the 1995 James Bond film GoldenEye, which was performed by Tina Turner. Adam Clayton and Larry Mullen, Jr. did a rework of the title track of the movie Mission: Impossible in 1996.Bono loaned his voice to "Joy" on Mick Jagger's 2001 album Goddess in the Doorway. Bono also recorded a spare, nearly spoken-word version of Leonard Cohen's "Hallelujah" for the "Tower of Song" compilation in 1995.
Aside from musical collaborations, 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. His poem "A Thanksgiving Prayer" was used as video footage during the band's Zoo TV Tour.
