Hot potatoes

Small pick ups appear in the autumn with a kind of tin pizza oven going in the back, to bake sweet potatoes in. They then crawl round the houses with a taped song-like chant belted out of a loud speaker: "Who will buy my sweet potatoes?" kind of thing. When I first heard this it reminded me of the call to prayer. I heard one the other night, in the distance - reminded me how easy it is to get the wrong message.
