SIR Bruce Forsyth believes the world of showbusiness is as thrilling as ever as he described his audience at Glastonbury as the best ever.

The entertainer says he is now "jazzed" up for the next series of Strictly Come Dancing - and said London mayor Boris Johnson would be a "wonderful contestant".

At the age of 85, Sir Bruce was one of the oldest performers to ever play at Glastonbury when he took to the stage this summer.

He said his gig, as well as other work, has left him excited about the next series of the dance show in the autumn. "I usually go into it cold without having any other things to do that have jazzed me up a bit, make me feel like working. So I'm looking forward to this series I think more than any other one I've done for the last five or six years," he said.

He remained tight-lipped about this year's contestants but said he would love to see Mr Johnson take to the floor. "He'd be a wonderful judge and he could even do my job," he said.

Sir Bruce added: "I know of all the rumours. Everyday the newspapers come out with another name they say is doing the show.

"Whether they are or not I don't know. And if I did know I wouldn't tell you."

He said Glastonbury is something he will never forget, adding: "I was the oldest person in the whole county, and there I am going on there and they were the best audience I've ever had."
