The tour was divided in two legs in the United States, West Coast and East Coast, and a gig in the UK at the Knebworth Festival.
The other two songs from Wish You Were Here (the title track and "Welcome to the Machine") wouldn't be played live until 1977.
The last gig of the tour was as the headliner of 1975 Knebworth Festival, which also featured Steve Miller Band, Captain Beefheart and Roy Harper (who joined Pink Floyd on the stage to sing "Have a Cigar").
[1] Knebworth was the last time the band would perform "Echoes" and the entire The Dark Side of the Moon album with Roger Waters.
The second set consisted of the entire The Dark Side of the Moon album with "Echoes" performed as an encore.
