Sweet & Sour Baked Beans

Having a large crowd over for a Father's Day barbecue?  This baked beans recipe could feed an army!

2 large cans (42 oz.) pork & beans
2 cups catsup
1 pound bacon, cooked until crisp  and crumbled
2 tablespoons Worcestershire sauce
1 large onion, chopped
2 small cans (8 oz.) pineapple tidbits, drained
3/4 cup brown sugar

Mom's only directions are "bake in slow oven 2-3 hours".  I'll let you decide what "slow" means, but for me it was 300 degrees.  Make sure you use a very large covered dish.
