Duets!
It’s not surprising that a two-person musical comedy about marriage would include lots of duets. In fact, if you’re looking for musical comedy duets, go no further. We have six(ish):
We Made Kids
Behind The Wheel
Main Line Philly Sex
Waiting Up (though primarily Clay’s song)
Dating
Do It All Again
(Clay also has dialogue and sings at the very end of Anymore, Anne’s opening number.)
