(John Phillips)
Boys and girls have a good time together;
Boys and girls, you know they抮e 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.
[ Lyrics from: http://www.lyricsfreak.com/m/mamas+the+papas/boys+and+girls+together_20549823.html ]
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抮e birds of a feather.
(Are birds of a feather...)
