ROCKER Ozzy Osbourne played an intimate gig thrilling Bucks fans with his brand of 70s heavy metal.

The Chalfont St Peter-based star played with his band Black Sabbath at Aylesbury Civic Centre as a warm up concert before his appearance at the Download festival in Donnington Park.

The set list for the show, limited to 1,000 tickets and for one night only, comprised of Sabbath classics, such as War Pigs and Paranoid.

There had been rumours that the show had caused a power cut at the centre the following day when Aylesbury Grammar School pupils were about to sit their exams.

However, Aylesbury Civic Centre has quashed this, claiming that all the equipment had been stringently tested, and was not capable of causing a blackout.

Mr Osbourne, of Welders Lane, was also preparing for a tour of the United States.

The Ozzfest series of festivals are organised by Ozzy and his wife Sharon, and are taking place at venues across America from July 15 to the beginning of September.

Mr Osbourne will be performing with Black Sabbath and topping the bill.

Music press reports suggest Mr Osbourne is undertaking the concerts to shake the image he has gained in recent years due to his antics on the cult US TV show, The Osbournes.
