In the DVD version, right after the 'Aow' (in the intro) he also takes the mic to his mouth and you can hear another 'ahaaaa' or something similar. In the BBC version you see him take the mic to his mouth but there's no ad-lib.
Great stuff, I've always wanted such a fanmade DVD. There are loads of angles in both versions and by combining them you should get a really good concert. I'll be sure to check that out when you'll post it. What about the quality difference between the two? How are you managing that? And what audio are you using? The DVD audio? I specifically like the pasted ad-libs on that one.
