I love that programme, too. I always suspected it was a Daddy and daughter show, so I Googled the cast and was chuffed to discover the Tig's Daddy really is the guy in the show. It's even voiced by her big sister, so thumbs up for being authentic in my book.
If you're interested (and sad like me), here's a link to save anyone Googling it...

PS: I cannot stand Mr Tumble and his other omnipresent shows. I know I've said it before, but have you ever noticed he never has the same friends on twice? (Phoney 'tig'.)
