(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...)
