Well, comet, I hope you really can live on love because it would be so inexpensive! This song which keeps coming back to me in snatches came from either Harold Rome's Pins and Needles (in the 40's) or from another political musical Pens and Pencils. Additional words I remember are: You've gotta keep that big bad wolf away

from the door before he gets chummy.

You've gotta.......three square meals a day

Cause you can't make love on an empty tummy...

Did you ever have a duet with your tummy which growls for food while you're cooing and wooing? What cacaphony! Good luck on loving without eating.
