In a large bowl, combine the flour, sugar, baking powder and baking soda. Cut in the butter until the mixture resembles coarse crumbs. Combine yogurt and 1/4 cup milk; stir into crumb mixture just until moistened. Knead in the cherries and chips.
On a greased baking sheet, pat the dough into a 9 inch circle. Cut into 8 wedges; seperate wedges. Brush with the remaining milk. Bake at 400 for 20-25 minutes or until golden brown. Serve warm.
