An early version of the song “Dogs” from the 1977 album Animals, this version was recorded in 1974 at the Wembley Arena. It is notably different from the album version, the lyrics are similar but different (far more words), the tempo is slower and the instrumental sections are longer.

Once in a while I would find something uncomfortable to sing. The first lot Roger wrote for “Dogs” when it was called “You Gotta Be Crazy”, were just too many words to sing. … “Dogs” had so many words, I physically couldn’t get them in. [We] just cut out two-thirds of his words, to make it possible rather than impossible.
David Gilmour, in 1992

It was included as a bonus track on the 2011 reissue of Wish You Were Here.
