A good analogy, Genie. I, too, would only not do songs that were totally unsuitable. I was once requested to do the one by Julio Iglesias and Willie Nelson - "To all the girls I've loved before". As a straight woman it just felt too ridiculous. Although I have no problem doing tradtional ballads from a man's point of view - such as "The Newry Highwayman" - well there's a slew of them out there. Ditto for songs that take an entire band do do well!
