Walk On is the perfect example of a very good song ruined by excessive/wrong stage props and choreography. When whatever surrounds the song becomes more important to the band than the song itself, the song has failed.
"David Bowie was with us one night. We were all such students and fans of his and we asked his advice on The Fly. He said, 'Do you really want me real advice?'. We said, 'Of course!' He said, 'Re-record it.' He was right but we had run out of time. It took us fifteen years to really get it right live."
- Bono on The Fly

The album Songs of Innocence used to start with 'This Is Where You Can Reach Me,' which was always supposed to be the first song. U2 then changed this to Raised by Wolves, but ultimately decided to "put the songs first", just like on Joshua Tree.
