Children's TV stars The Krankies have revealed details about their private lives, confessing to indulging in "swinging" in the 70s and 80s.

Comedy duo Ian and Janette Tough, both 64, who soared to fame on children's TV show Crackerjack, described their "active" relationship and how they once were nearly swept out to sea.

In an interview on BBC Radio Scotland's Stark Talk programme, Janette said: "We had a little boat, it was only a little 12ft boat and we went out for Sunday lunch one day. We thought we would get a bit romantic on this boat out at sea and we nearly ended up in France."

The pair, who met aged 18 and married when they were 21, confessed to presenter Edi Stark to having the occasional "ding dong" with other people when they were on tour.

But Janette said: "We weren't behind each other's backs. We knew what each other was sort of up to."

Husband Ian said: "But then we thought, 'we are playing with fire here'. What we started to worry about was that the other people were getting jealous."

The couple said they had escaped any publicity over what they were up to, which would be very different now. "It was not years or months or anything like that, it was when we were on tour," Janette said.

The couple also told how they once borrowed rock band Status Quo's bus - which they returned "trashed".

Ian said: "Status Quo lent us their coach once. When we gave it back they said, 'blinkin' heck, it's worse than if we'd lent it to a rock show'. And this was for a kids' show."

The couple, who both started in pantomime, are appearing with John Barrowman in Robinson Crusoe at Glasgow's Clyde Auditorium.
