Preheat oven to 350°. Unroll crescent rolls; separate into triangles. Place 1 peach quarter on wide end of each triangle; roll up triangles around peaches, starting at wide end. Place, point sides down, in a lightly greased 13- x 9-inch pan.
Stir together sugar, butter, and cinnamon, and drizzle over rolls; pour soft drink over rolls.
Bake at 350° for 45 minutes or until golden brown and bubbly.
Note: For citrus-flavored soft drink, we tested with Mountain Dew.
