My mom used to sing "Don't bring Lulu" too. If memory serves it goes, "You can bring pearl she's a darn nice girl but don't bring Lulu. You can bring 'pet she's the best girl yet but don't bring Lulu. Lulu is a smarty who breaks up every party. Lulu always wants to do what us boy's don't want to do. Hulabaloo-loo don't bring Lulu. She'll come by herself".
