"Walk On" scored U2 another Grammy for Record of the Year. This song was supposedly inspired by Aung San Suu Kyi, a nonviolent Burmese political activist who has been under house arrest off and on since 1989.
But many people feel the song is a tribute to someone nearing the end of his life (possibly Bono's father), who realizes that love is really the most important, and only, thing to take on his journey. ("You're packing a suitcase for a place none of us has been/A place that has to be believed to be seen . . ." and "Home . . . I can't say where it is but I know I'm going home.")
During the Elevation tour dates after 9/11, the band took NYC firefighters and police officers on tour with them and brought them onstage during this song, which adopted a special meaning after the terrorist attacks.
