BILLY Connolly is to do another stand-up tour this year.

The Big Yin, who has Parkinson's disease, announced yesterday that he is to perform 13 dates in Canada.

Billy, 72, has been performing in Australia this year and his native Scotland in 2014 after vowing to keep touring despite his Parkinson's.

He said: "I'm starting to have problems remembering things but who doesn't when they get to my age?

"Sometimes you get blanks. The curtains fall down in front of your eyes so you just keep on talking until you remember your material.

"I've had a good run of it, to get to my 70s and still be standing upright."

The Glasgow-born star revealed in 2013 that he had had surgery for prostate cancer.

Tickets for the Canadian tour are expected to be snapped up when they go on sale later this week.
