They definitely only played it once, and it didn't seem strange when you were there. The crowd had been on their feet and clapping for the whole of the encore songs (in fact the whole gig had had a good atmosphere generally) and it was a good rocking song to finish the show with. When they started it, I thought it might be Solid Rock but once it got going it was obviously a new song. I am guessing they moved it to the end so that the crowd were at their most lively for the filming maybe?
I've not seen any recordings in circulation of any of the Sheffield shows - nor the other show I saw on that tour at Gateshead 92 - which I am sort of pleased about. I think hearing a (probably poor quality) recording would spoil my memories of the shows somehow.
As I said in my original post, we did get some rarities that particular night, although early in the tour they mixed the set up a lot more before it settled down. Iron Hand came over really well as a new song, WICTY which I already knew from the Hillbillies (I remember Danny coming down from his percussion rig and dancing around the stage with a tambourine during this one) and then Setting Me Up in the encores.
OES itself also sounded really good - I think Calling Elvis was the only new song that I knew at that point.
