Problems were probably inevitable at such a large-scale, one-shot
performance. The concert started smoothly enough, with the introductory
acts (The Hooters, in case you were wondering why they're credited, along
with James Galway and The Band, plus a German group) and the Scorpions'
performance of ``In the Flesh.'' But the microphones died completely during
``The Thin Ice'' -- Roger just waved at the crowd and did a little tap
dance to keep them entertained. They got the mics working again mid-way
through ``Another Brick, pt.1,'' but only at low power; the crowd
periodically screamed ``louder, louder!'' Full power was finally restored
for ``Empty Spaces,'' and continued without a hitch for the rest of the
show.
The other well-known blooper was on Sinead O'Connor's rendition of
``Mother.'' As I understand it (second-hand), as The Band began to sing the
chorus, she lost her place in the song and began to sing the next verse!
These mistakes were ``cleaned up'' on the album and video releases by
splicing in footage from the previous day's dress rehearsal, and from an
emergency redo of the entire concert the company did, right after the
official performance.
