Engelbert Humperdinck will sing a "soaring ballad" at this year's Eurovision Song Contest, it has been announced, in a performance staged by choreographer Arlene Phillips, UK Press Association reported.

The 75-year-old star will be accompanied on stage by guitarist James Bryan, who is known for his performances with Nelly Furtado.

Humperdinck, who was unveiled earlier this month as the surprise choice to represent the UK after boy band Blue finished a disappointing 11th last year, said: "I have my eyes on the prize with my song, Love Will Set You Free."

"I'm very proud of the song and with the nation behind me, I feel ready and look forward to the rollercoaster ride that is Eurovision!"

The BBC had already announced that an unnamed song was being written by Sacha Skarbek - who teamed up with James Blunt to compose his global hit You're Beautiful - and Grammy-winning producer Martin Terefe.

The track has now been recorded in London, Los Angeles and Nashville.

Veteran singer Humperdinck, who enjoyed his last top 10 hit 42 years ago, will be representing the UK at the 57th Eurovision Song Contest, taking place in May in Baku, Azerbaijan.
