THE new Beatles Rock Band game is tipped to be one of the biggest-selling of all time.

The game, which allows players to “play” live on stage with the Fab Four, is expected to top global toy charts this Christmas.

Last night, to mark its release at midnight, retailer GAME hired out The Cavern for an official launch party.

GAME spokesman Neil Ashurst said: “The Beatles Rock Band has certainly caught the nation’s imagination and is likely to be the most successful title in the Rock Band stable.

“The game will have a cross-generation appeal – seasoned Beatles fans can step into the shoes of their heroes and a new generation of younger fans will be introduced to one of the country’s most iconic bands.”

But Sir Paul McCartney has revealed he has still not played the game.

“I haven’t tried it. When you go to a demo they play it and I go ‘God, that looks hard’,” explained the Fab Four’s bass player and vocalist.

“I think you either don’t embrace the modern day or you do embrace it,” he said.

“For instance, I held out on mobile phones for years. I could see everyone using them, I thought they were poncy. But then I got one and thought ’This is good’.
