I thought the pig dumb then and now. And if truth be told, I didn't even like the concert at the time, I slammed it in a letter to a German music paper and they printed it (headlined as "Pink Rubbish") and the next thing I get is physical violence threats from all those peacenik Pink Floyd fans.
What put me off was the Floyd's seeming arrogance at the time, they came across as totally aloof, they did not even introduce Snowy White as their 2nd guitarist. No stage announcement the whole evening, they first played Animals complete, then had a break and proceeded to play Wish You Were Here (the album) complete (with some nice extended Gilmour solos) and then left stage without a word to encore perdictably (again without a word) with Money and Time. In hindsight this was of course the time where Waters felt the alienation from the audience especially strongly which then prompted him to lick his wounds with The Wall (which I find hugely overrated to this day, I'm a Wish You Were Here guy myself with its krautrockish ambience music).
But that was long ago, these days I can appreaciate Mason's heartthrob drumming, the voice of Gilmour's English blues school guitar playing, Wright's warm keyboards and Water's acerbic wit. While I find a lot of Water's solo work (and I include The Wall with that) as unbearably self-centered and masturbative, Floyd without him degenerated to just a pleasant sound landscape with an excellent guitarist, but without any real lyrical depth and or that Waters edginess which prevented Pink Floyd from becoming the Moody Blues II and kept you on your toes as a listener.
