Stir together cream cheese, blue cheese, radish, mustard, mayonnaise and chutney. Roll each bread slice with a rolling pin to flatten. Spread one side of each with 2 tablespoons cream cheese mixture and top with 1 tablespoon sausage. Place 2 asparagus spears in the middle of each prepared bread slice and roll up. Place each roll, seam side down, on a baking sheet and brush lightly with butter.
