Lyrics:

Wipe out the problems of past society
(Shack up! Shack up!)
Is that we can live together baby, unless you can feel the heat
(Shack up! Shack up!)
We can love together, work together, sleep together
(Shack up! Shack up!)
So why can't we live together?
And shack up baby, shack up

You can talk about the wedding ceremony
(Shack up! Shack up!)
And I know it's just a phony
(Shack up! Shack up!)

Marriage is a big commitment, yeah
(Shack up! Shack up!)
I bet you find life hard to live with
(Shack up! Shack up!)
I love you now, but that don't say I'm gonna love you forever
(Shack up! Shack up!)
So I don't believe in alimony, okay, love?
(Shack up! Shack up!)
Though I think we'd ought to
Shack up baby, shack up
