Gilmour + Wright - Breakthrough
https://music.youtube.com/watch?v=PzTW9Wdl1P8
This is actually a song originally written and recorded by Richard, but they played it live as part of a Gilmour show.
This video is notable for reuniting Gilmour, Wright, and Michael Kamen, three of the key musicians in The Wall. Adding to them Dick Parry, their longtime collaborator, session and touring musician who recorded saxophone parts in The Dark Side of the Moon, and various other #PinkFloyd albums.
