Zippy is Tongue Tied - S17.E20

Zippy's behaving oddly and not speaking to anyone because he's tongue-tied. Denise reads a story called 'Cherp Finds His Voice'. Then Zippy, George, Bungle and Geoffrey go to a concert that some children are performing at the village hall. Rod, Jane and Freddy sing "Everybody's Tongue-Tied Sometimes". Zippy performs "I Had A Little Nut Tree" and everyone enjoys his little poem and Zippy doesn't feel tongue-tied anymore.
