Bono wrote the lyric of the 1988 song "All I Want Is You" as a meditation on the idea of commitment. He later said, "clearly about a younger version of myself and my relationship with Ali," and added that by nature he was a wanderer, not a family man, and that "The only reason I'm here is because I met someone so extraordinary that I just couldn't let that go." U2 lyrics usually have several possible levels of interpretation, and it is not always possible to definitively ascribe Hewson's influence upon them, but music writer Niall Stokes believes that inspiration from Hewson is pronounced throughout the group's 1997 album "Pop", particularly on "Staring at the Sun", which he believes reflects her Chernobyl Children's Project involvement and the feelings of both danger and hopefulness that it triggered in Bono. Stokes also believes that the 2000 song "When I Look at the World" is an explicit acknowledgement of Hewson's strength and commitment as exemplified by that Chernobyl work, while others think it is about Jesus or God. Bono has seemed to deflect those interpretations, saying that song is in part a hard-edged look at himself from the eyes of one losing faith. In any case, Bono has said that he does not feel constrained in his writing or interviews by what Hewson might think, as "[she doesn't read newspapers. Or listen to the radio. There's a mysterious distance between us." Not known for being musical herself, Hewson did perform Lady Gaga's "Telephone", as a duet with her husband, to serenade their daughter Eve at her 21st birthday celebration at a club in Las Vegas in 2012.
