The February/March issue of British Rock Candy covers a story about the final days of MK IV. The boss of the magazine witnessed the two gigs at Wembley Empire Pool 1976.
I read it last week, there wasn't anything new.
I read the 2nd Wembley show was certainly better than the first show.
I haven't seen reviews for Glasgow and Leicester.Glenn has said that he didn't get a wink of sleep on the UK tour and was apparently 'howling like a dog' come the last show.
if I remember correctly those UK tour shows aren't that much worse than the US ones...but they are not as awesome as the first ones in New Zealand and Australia.
Still better than what most musicians nowadays could do.
