On another thread somebody said everyone in the Musgrave story made the wrong choice - and it's just as well they did, as if they hadn't there'd be no song. It's certainly hard to imagine a happy ending for Musgrave -

"Oh, well I like your bed, he said,
And well I like your sheets,
But I wouldn't know about your fair lady... oh, you mean this fair lady! Now, I know how this must look, but there's a perfectly simple explanation..."

Something Little Musgrave shares with Lucy Wan/Edward is the way it invites sympathy for someone who's in a bad situation that's only going to get worse - you've done that, and what the hell are you going to do now? Sympathy doesn't mean approval or thinking they're a great guy, just fellow-feeling - for a while the song puts you in their shoes.
