In a small bowl, dissolve yeast in warm water. In a large bowl, combine the milk, butter, sugar, egg, salt, yeast mixture and 3 cups flour; beat on medium speed until smooth. Stir in enough remaining flour to form a soft dough (dough will be sticky).
Do not knead. Place in a greased bowl, turning once to grease the top. Cover and refrigerate overnight.
Punch down dough. Turn onto a lightly floured surface; divide in half. Roll each into a 12-in. circle; cut each into 12 wedges. Roll up wedges from the wide ends. Place 2 in. apart on greased baking sheets, point side down. Cover with kitchen towels; let rise in a warm place until doubled, about 1 hour.
Bake at 350° for 15-20 minutes or until golden brown. Immediately brush with additional melted butter. Remove from pans to wire racks to cool.
