What are people's takes on when bands rework one of their tracks for the live stage?
I'm talking about speeding it up, or slowing it down, or playing it in a different key etc.

I saw Sparta last night and whilst they were absolutely superb, the played a toned down version of Collapse which happens to be my favourite song of theirs. It wasn't bad but I think it lost a lot of its punch.

I'm happy for bands to change stuff live, it can be boring to hear the albums note for note but i think there's certain songs you should just leave alone.
