I vaguely remember Sara and Hoppity as a child back in the 60's. I think it was on saturday mornings with Alan Taylor presenting.
Sara and Hoppity was a puppet show with a girl called Sarah and a naughty toy called Hoppity who had one leg longer than the other. Hoppity used to rant and shout "Dilly dum, dilly dee, dilly dum, dilly dee". Probably not very PC now.
