Led Zeppelin have rejected continued requests from the makers of Guitar Hero and Rock Band to release a game inspired by the group, it's been revealed.

According to a report in the Wall Street Journal, the band are not comfortable with giving away the master copies to their songs.

"It ain't about the money," explained Peter Mensch, a partner at Q Prime Management, who manage guitarist Jimmy Page.

Pressure has grown on Led Zeppelin to return to the public arena since their reunion concert in London last year.

A number of bands have released special edition versions of both games, with Guitar Hero: Aerosmith hitting shops last weekend.

Metallica have also been linked with a future edition of the game, which is expected in Spring 2009.
