Engelbert Humperdinck will be carrying a prized gift from Elvis Presley to bring him luck as he performs in the Eurovision Song Contest tomorrow night.

The crooner is one of a handful of people from the King’s circle of friends who were given one of his TCB necklaces, which stands for ‘taking care of business’.

And the 76-year-old will have the treasured trinket with him when he represents the UK in Baku, Azerbaijan, against other acts from around Europe.

A source said: “He has it in his pocket all the time, to bring him luck.

“Only a few exist and they are priceless, Elvis only gave them to his friends. He wants to channel some of his charisma and spirit for his Eurovision performance.”

Engelbert will be up against acts such as Irish contestants Jedward when they perform at the kitsch show in Baku’s Crystal Hall.

According to betting comparison site Oddschecker.com, Engelbert is now fifth favourite, although the bookies seem undecided over the UK’s chances for success, with current odds ranging from 20/1 to 12/1 on The Hump to win.

Sweden is still the clear favourite at a best price 11/8, with singer Loreen set to perform Euphoria, which has been in 14 European charts already this year and No 1 in four countries.

‘Taking Care of Business’ was a personal motto of Elvis, and also the name of the main group of musicians who formed his backing band. He had the initials TCB painted on the tail of his personal jet, along with a lightning flash.
