Well, Axe didnt do much during the middle section of Under The Weeping Moon. The album version has all sorts of drum fills and snare rolls. I guess he was trying not to fuck it up, because it seems pretty challenging.
I would suggest to you that he didnt do these drum fills, simply because it would have spoiled the ambience of what mike and per were doing during that part. the album version does have these extra drum parts, but they are very quiet, it would have been extremely difficult to replicate that live as the volume on the drums would have had to have been dampened severely, this potentially messes things up with they have to be re-set.
I very much doubt he didnt do this because he doesnt have the ability to do so.
