According to reports, Paul McCartney may be a last minute addition to the London leg of the Live Earth events, taking place this weekend, of course. He's not down on the line-up, but he's thought to have been asked to take part. A 'source' claims an appearance is not out of the question, and is quoted as saying: "It's true that Paul has been asked to take part. He said that the cause is very close to his heart and he's very impressed with what Al Gore's been doing to highlight it, but he's still deciding whether he can do it at the moment".
Elsewhere in Live Earth news, 5,000 extra tickets have been made available for the Wembley show, and are available from http://www.livenation.co.uk. Well, they were as I wrote this. I expect they'll sell out pretty quickly.
