Come and knock on our door. We've been waiting for you.
Where the kisses are hers and hers and his, three's company too.
Come and dance on our floor. Take a step that is new.
We've a lovable space that needs your face, three's company too.
You'll see that life is a ball again and laughter is calling for you.
Down at our rendezvous, three is company, too.
