A massive open air concert in Hyde Park will be the climax of Safeway's six-week World Favourites promotion. The retailer is looking to top its Pavarotti in the Park event last year with a line up of Diana Ross, Rod Stewart, Gabrielle, Ronan Keating and Dame Shirley Bassey at Safeway Picnic 2002 on Saturday June 29. Proceeds from the event will go to the Princes Trust charity. Tickets priced £20 went on sale at Safeway outlets on Thursday, although they will also be available through other box office outlets from April 18. Commenting on the event Safeway marketing director Karen Bray said: "This year we're offering a selection of World Favourites to customers across the country, so it's fitting that some of the most popular stars in the world are gathering on our behalf." The World Favourites promotion will involve a line-up of Italian, American, Indian and other Asian dishes, together with British summer favourites, supported by offers, instore sampling and PoS. {{NEWS }}
