I don't have any boots where David is straining to reach notes in SOYCD. And bootlegs don't have the added benefit of being tinkered with in the studio to correct flat notes or what have you. Those are raw tapes of the concert as it was happening. I don't disagree that they sang the songs they did for a reason, but that doesn't mean that either party couldn't also sing well, a song that the other party sang. For example, on Animals, Roger sang the last two verses of Dogs but live, David sang all but the very last verse, the one that starts with "Who.....". It doesn't sound off at all to have David singing that part, even though Roger sang it on the record.

I would NEVER want to hear David sing Sheep or hear Roger sing Fat Old Sun, but there were many other songs that I do feel could have been transposed for the other voice and it still be a pleasant listening experience.
