For Waters' worldwide 2010–2013 "Wall" tour, the song was transposed one whole step down, from D to C. This is commonly done in live performances when a singer has difficulty reaching the highest notes in the song's original key. During the intro of the song, Waters clapped to the beat and in some cases shouted, exhorting the audience to clap along and "have a good time, enjoy yourselves", which might be considered ironic, given the paranoid tone of the actual lyrics. Again, he did not play bass guitar, instead gesturing with a prop submachine gun at various points throughout the song.
