I often used to watch Supergran when it was on in the 1980's. This was usually screened on ITV on Sunday at around 5-6pm, teatime.
It is about a Gran who is given special powers and when people needed help or were in trouble, they called on her to sort them out, mostly involving crime.
Each episode lasted 30 minutes and usually broke off for some adverts in the middle, which was quite annoying.
Supergran was played by Grudun Ure and the cast also included Ian Cuthbertson and Bill Shine. Each episode had a special guest star. The Supergran theme song was sung by Billy Connolly.
Although some people who I know thought this was silly, I enjoyed some of the episodes and would be good to see some again.
