Extra tickets for McCartney gig

Sir Paul has waived his fee to take part in the event

An extra 4,000 tickets have gone on sale for Sir Paul McCartney's summer concert in Liverpool.

Five hundred of the tickets - dubbed the best seats in the house - are being made available to charities and community groups in the city.

Organisers hope the £75 tickets could be offered as competition prizes to help the groups raise money.

The Kaiser Chiefs are the first guests to be announced for the concert, which is being held at Anfield in June.

Showpiece event

Organisers said further names would be announced in the next few weeks, including a "very special international superstar".

The concert - dubbed Liverpool Sound - is one of the showpiece events of the city's Capital of Culture celebrations.

A total of 25,000 tickets for the event were sold in a ballot last year on the strength of Sir Paul's name being attached.

Tickets for the event have been sold on eBay for up to £1,200 and organisers wanted to ensure that communities in the city could benefit from the latest allocation.

Phil Redmond, creative director of the Liverpool Culture Company, said the tickets could not simply be given away.

"We just have to make sure that the box office numbers stack up," he said.

"We are actually offering the best seats in the house for community groups to buy and then they should be able to sell or raffle them off."
