British heavyweight pro boxer Tyson Fury has the reputation of being an entertaining figure both on and off the ring. The 27-year-old faces boxing legend Wladimir Klitschko for a shot at his WBA, IBF, and WBO titles on Saturday in Dusseldorf, Germany.

On paper, this boxing bout looks one of the biggest ones after the 'Fight of the Century' earlier this year between Floyd Mayweather and Manny Pacquiao.

The bout got a major promotion earlier this year as Fury made headlines after appearing at a press conference in the cape of comic superhero 'Batman'. The undefeated boxer's antics drew a lot of attention, and Klitschko also mentioned about enjoying the entire act.

Fury continued his entertaining act, this time on the ring, as he took up the microphone to sing Bette Midler's famous number "Wind Beneath My Wings", albeit a modified version. It took place during the Open Workouts on Wednesday at the Dusseldorf Airport in Germany.

If having open workouts in an airport was bizarre, Fury took it to a whole new level. Possibly, an event like this occured for the first time in the history of pro boxing where the challenger rendered a number to thrash-talk the champion.

The modified lyrics from Fury were: "You are the one with all the glory, and I am the one with all the strength" and "I am the one with the new gold ring. And I'll be the one with all the belts". 

The British boxer is 24-0 in the pro boxing circuit, while the 39-year-old Klitschko has 64 wins from 67 fights in his career. But Fury exuded confidence. "I am going to show everyone why I will be the next heavyweight champion on Saturday night. [There is] No fear, I have just the belief. It's about how much much fight you got inside. I will be singing a song in victory."

When asked whether he will still sing if he loses, Fury said: "I won't lose. We don't sing songs in defeat, we only sing songs in victory."

Here is Tyson Fury's version of "Wind Beneath My Wings", dedicated to Wladimir Klitschko:
