Black admits to festival fears

Jack Black has revealed that he is "scared" about performing at this year's Leeds and Reading festivals with his band Tenacious D.

The actor and musician said that the crowds expected for the two festivals, which take place from August 22 to 24, are bigger than the audiences he usually plays for.

"I'm very excited - it's legendary," he said. "Tenacious D live at Leeds! I'm a little scared as we don't usually play places that big. It's going to be a lot of people - more than 1,000! It should be interesting."

Black confessed that he is bracing himself for the British weather: "What do I have to expect? Kind of muddy maybe - I've heard sometimes it rains."

The Kung Fu Panda star added that he wants to perform with the White Stripes.

"I'd like to rock with Jack White - the Black and White! It will probably never happen as we're like the yin and yang that never come together," he explained.
