We were never a band that did 96 takes of the same thing. I had heard of groups that were into that kind of excess around that time. They'd work on the same track for three or four days and then work on it some more, but that's clearly not the way to record an album. If the track isn't happening and it creates some sort of psychological barrier, even after an hour or two, then you should stop and do something else. Go out: go to the pub, or a restaurant or something. Or play another song.
