Something lost...something found

The Pretenders' song Hymn to Her was mentioned at a recent Economic Society of Australia symposium that I attended on Cost-Benefit Analysis. It was cited as a quintessential economics song: opportunity cost sprang to mind. But to my mind it is more of a PM song (well, its even more than that: one of the great ballads of the 80s): "something is lost--something is found"...day in day out for busy PMs!
