Royal wedding set for download

Prince William and Kate Middleton are set to storm into the charts after tying the knot, with the almost instant release of their wedding ceremony for download, record producers said overnight.

An audio recording of the entire ceremony will be available within hours on Apple's iTunes and other leading online stores.

The recording will be released in shops worldwide six days later by Decca Records.

It will be "the first official royal wedding album ever to enter the worldwide charts", said Decca president Dickon Stainer.
