Whatever the merit of judging these performances there's no doubt that the tempo of TR was subtly altered some time ago to aid mark a little. Plenty of little 'greenies' in both performances, but also plenty of effort and still some good little fluid passages.
Gives us mere mortals some hope
Yes, speed is the only thing that has suffered (quite big time) for the last 15 years, especially since he was so fast previously.
Gilmour for example has not suffered much on the speed side cause pink floyd songs have always been pretty slow since the very beginning, contrarily to dire straits songs.
Regarding all the rest, touch, inspiration, is beyond imagination,
for example Telegraph Road final solo from 1992 was much faster than now obviously, but he is struggling now ?
I don't think so, actually the Barcelona final solo from this tour imo is much more enjoyable
overall to me than the much faster ones.
