Sir Paul McCartney is the latest big name to shoot a cameo for the hotly-anticipated Some Mothers Do 'Ave 'Em sketch for Sport Relief.
So what will the legendary Beatle be doing in his sitcom appearance? Well, somewhat understatedly, he’ll just be taking a stroll in a local park while chatting on his phone when he comes across Frank Spencer.

The beloved sitcom is making a return for one night only, with Michael Crawford reprising his famous role of Frank – last seen in 1978 – alongside Michele Dotrice as his long-suffering wife Betty.
Bond Girl Gemma Arterton will play their grown-up daughter Jessica.

Frank faces a desperate race involving a bike, rollerskates and a double-decker bus to reach the Olympic velodrome in time to watch her compete in the 10-minute sketch.
Other big name appearances include F1 driver Jenson Button, comedian David Walliams and cyclist Sir Bradley Wiggins.
