Pet Shop Boys criticize Live Earth

Pet Shop Boys singer Neil Tennant has spoken out against this summer's Live Earth concerts.

Tennant has also hit out against Bono for his politically active role.

He said: "The Princess Diana concert is fair enough, but I feel more uneasy about the

Al Gore thing. I've always been against the idea of rock stars lecturing people as if they know something the rest of us don't--it looks arrogant. It's not as if they have a private source of information. To state the obvious as if you are the only person that knows it is intellectually weak."

Of the U2 frontman Tennant told Yahoo!: "Bono uses his celebrity but in doing so he increases his celebrity. I've never even totally convinced that the rest of U2 feel comfortable with that."

The gig take place on July 7 in venues across the world.
