At the risk of getting tomatoes thrown at me, how about her singing "The Unicorn" or maybe "The Cat Came Back?"

Some others that might work for her are "Geordie," "Shool Aroon," "Come All You Fair And Tender Ladies," "Mo Mary," "Scarlet Ribbons," "Star Of the County Down," "Isle Au Haut Lullaby," "River," "Give Yourself To Love," "The Circle Game," and "Cornflower Blue."
