In a large mixing bowl, combine the cream cheese, sour cream, mayonnaise, lemon juice, Worcestershire sauce, dry mustard and garlic salt. Mix until the cream cheese is in dime-sized lumps. Fold in the crabmeat and mix well.
Put into individual crocks or ramekins, or into one larger, oven-safe serving dish, and bake at 350 degrees F for 20 to 30 minutes until heated through.
Serve with crackers or sliced baguette, raw veggies (carrot sticks, celery sticks and so forth).
