On that 1980 tour there was also a right old brouhaha, some say furore, when it was discovered that an entire gig - Birmingham? Liverpool? - had somehow been given completely over to fan club members. I'm not sure if that's true or if so how it would've happened but there was definitely a big old froth about it.
But yeah as I understand it, the 80 tour satisfied a hankering they had to return to the smaller venues of their earlier career, including a nostalgic Aylesbury Friars Club gig for which the ticket queue went twice around the entire globe. Or something.
The set list was approximately the same the whole tour with a few tweaks and seemed to make sense for that time. The most notable aspect of it was all the new stuff being done in one single block.
