does anyone know?

Hi everyone,
I was lucky enough to be on a live episode of Tiswas - I would love to see it back because obviously at the time there were no recording facilities and the show was aired live!
It was either 77 or 78 (I think more 78) The group on the show were Bilbo Baggins and the star guest was Eddie Kidd - Can anyone give me the episode or any ideas how I can find out which one it was, cos It would be soooo nostalgic to see it and how I looked when I was 13/14 years old!
Thanks Guys!
