Scissors Sisters will open this summer's iTunes festival in London, it's been announced.

The free event will feature a total of 62 bands over 31 nights at the Roundhouse in Camden.

Scissor Sisters, whose new album 'Night Work' is released in June, will headline the bill on July 1.

Tony Bennett is due to play on July 2 and Ozzy Osbourne on July 3.

Osbourne, who has never played at the Roundhouse before, told the Metro he was looking forward to playing "an intimate show there for the fans”.

Fans can register for a chance to get tickets to the event via the iTunes festival website.
