The best song for male and female I know of is "Waltz of the Wallflowers" by a duet called Small Potatoes. It won song of the year at Kerrville a few years back. Absolutely a smash! It has to be heard to be believed, and when you see them do it in person!!!!!! They do one called "Boy 'Round the Corner" that is very good, too. If you are not familiar with Small Potatoes, by all means get on the net and order some of their stuff. They are VERY good!!!
