NME wrote a longish thing about some bands and Coldplay at Isle of Wight, mentioning that they covered Lou Reed's "Perfect Day." This is what they said about Lou's performance:
"Earlier with the sun-setting, Reed himself played a well-received evening set. Joined on stage as usual by his Tai Chi master, the former Velvet Underground leader revisited early parts of his career including 'I'm Waiting For My Man' and 'White Light/ White Heat.'"
I don't have to tell you that I'm sad I wasn't there for that and that having your Tai Chi master with you on stage is incredibly Advanced.
