Dusseldorf - Having previously dressed as Batman for a press conference, Tyson Fury employed more theatrics on Wednesday by turning to song in the latest round of mind-games with Wladimir Klitschko.
World heavyweight champion Klitschko will defend his IBF, WBA and IBO titles against British challenger Fury in Dusseldorf on Saturday.
Fury, 27, ran into a press conference last September dressed as Batman, then called Klitschko 'a joker' to his face, but he grabbed the microphone for his latest stunt.
At a training event for the press at Dusseldorf airport, the 2.06m (6ft 9in) Fury seized the chance to show off his singing ability.
He adapted the lyrics of the Bette Midler song 'Wing Beneath My Wings' to include the words "I'll be the one with the belts".
"I was impressed," said Klitschko. "If it was down to singing, I'd have no chance. But things look different when it comes to boxing."
This is not the first time Fury has showed off his vocal prowess, having sung the same song when he beat Kevin Johnson of the USA in Belfast in December 2012.
He also sang a different song in the ring after beating US boxer Steve Cunningham in New York in April 2013.
Rob Stewart will sing before Saturday's heavyweight bout in Dusseldorf and Fury wants to seek out the Scottish crooner for a duet if he beats Klitschko.
"I will enchant the fans, perhaps with a duet with Rod Stewart," he told SID, an AFP subsidiary.
