During Waters' The Wall Live tour, Robbie Wyckoff sang Gilmour's vocals, and Dave Kilminster performed the guitar solos with G E Smith on bass, both of them atop the wall, as Gilmour had been in the original tour. During the performance of 12 May 2011 at the London O2 Arena, David Gilmour appeared as a guest during this song, and both sang the choruses and played guitar from the top of the wall, echoing the original Earls Court performances. The song contains one of the show's most memorable moments, when, at a specific point of the final guitar solo, Waters steps toward the wall and pounds it with his fists, triggering both an explosion of colours on the previously dark-grey screen projections and a collapsing wall.
