Sir Bruce's Swan Song?

Could this year be Sir Bruce's swan song? Is he ready to give up? His friend Ronnie Corbett thinks it might be.

The Daily Express reports that Ronnie speculated to The Sun: "Bruce seems to thrive on entertaining but whether he will thrive after this series of Strictly I don’t know. He must get tired. I think after this series he will give himself a Brucie Bonus... Every Saturday is gruelling. It is really hard going. It is not something I could do each week on Saturday nights now... Bruce is a special breed and his talents are very diverse as he can dance and play the piano. But Bruce does not walk down the stairs now — he comes down from the side like a dancer."
