When Elvis Presley walked in to Sun studios in 1953 who could ever have known that his success would spawn a whole new career choice of 'Elvis Impersonator', and that career choice would itself hold national and international competitions as well as having its own Hall Of Fame?
There are some famous singers who could be classed as Elvis Impersonators, such as Freddie Starr or Les Gray who adopted the persona of Tulsa McLean, but my own favourite is Sweden's Eilert Pilarm.
I will let you make your own mind up about Eilert, he has had hundreds of thousands of YouTube hits, and he has reputedly played at Graceland. His songs were regularly featured on John Peel's radio show, and he was the Best Swedish Elvis Impersonator of 1999. It is unknown who the opposition were!
