Elvis clones attempt record
By Evening Standard

It will be hard not to step on some Blue Suede Shoes later this month when Selfridges attempts to set the world record for Elvis impersonators performing at one venue.
The Oxford Street department store hopes to attract more than 100 Elvises to perform Love Me Tender in full costume, in tune and in harmony, on Sunday 17 April.
There is currently no record for a mass Elvis show but the Guinness Book of Records has agreed to reognise it as a new category.
The record attempt will also take the form of a talent contest, with the best Presley in line for prizes including the chance to perform at a major Las Vegas casino.
Other would-be Hound Dogs should call Gerry Cottle Jr on 020 7404 3000, or turn up at Selfridges at 9.30am on 17 April, in their own costumes and with the words to Love Me Tender memorised.
