In 1982, when the film Pink Floyd The Wall was released, this was our first chance to hear "When The Tigers Broke Free" I had a bootleg vinyl record of Music From The Film Pink Floyd The Wall. Basically, the movie soundtrack with "When The Tigers Broke Free" and Bob Geldolf's versions of "In The Flesh!" and a few others. There were also the 45 rpm versions of Music From The Film with "..Tigers..." and "Bring The Boys Back Home". The original track listings of The Final Cut was released without "...Tigers..." Then we had to wait several years for Pink Floyd to put "...Tigers..." on special editions of The Final Cut.
I also have the Japanese HDCD version of Final Cut, which includes "...Tigers.."
I never learned why it was not included in the Shine On box set.
