Considering a duet is a man and a woman (duo is two of the same):
"Leather and Lace" by Stevie Nicks and Don Henley
"Stop Draggin' My Heart Around" by Stevie Nicks and Tom Petty
"What Kind of Fool?" by Barbra Streisand and Barry Gibb
Good choices.
However, a duet doesn't have to be a man & a woman.
http://dictionary.reference.com/browse/duet gives definitions from multiple sources...no definition of duet specifies it has to be a man & a woman.
