(John Phillips) Boys and girls have a good time together; Boys and girls, you know they're birds of a feather. Like two sides of a coin, They are forever joined. Heads or tails---choose one or the other; Be my friend or be my lover. Boys and girls (boys and girls) should always have someone; Boys and girls (boys and girls) should never be lonesome. (Should never be lonesome) Heads or tails---choose one or the other; Be my friend or be my lover. Like two sides of a coin, They are forever joined. Boys and girls (boys and girls) have a good time together; Boys and girls (boys and girls), you know they're birds of a feather. (Are birds of a feather...)
