Cook and Line find Captain HeyHo’s old guitar washed up on the beach. The captain insists that it cannot be hers, since it was washed overboard in a storm many moons ago. However, after seeing her name on the back of the guitar, she realises it is indeed hers and that it even has a name: Sheilagh!
After some persuasion, the boys manage to convince the captain to play them a tune. A fabulous musical number unfolds in the captain’s Cove, complete with backing vocals from Cook and Line.
