down the Dearne on a digestive,
up the Thames on a Bourbon,
down the Sheaf on a Garibaldi,
up the Don on a Flapjack.
down the Tyne on a Brandy Snap,
up the Wear on a Hobnob,
down the Severn on a Ginger Nut,
up the Lune on a Custard Creme.
down the Styx on a sunflower seed bun,
up the Lethe on a lemongrass stick,
down the Rhine on a Raisin Slice,
up the Seine on a Belgian Pancake.
