Thanks tyke51. I saw a lovely programme about Ronstadt, Harris and Parton last year - sadly Ronstadt has some sort of degenerative disease (once thought to be Parkinsons, though not now). I do prefer Neil Young's version though, with his ethereal voice.
I've followed the cosmological problems in New Scientist!
Congrats, BBM2. As I said earlier, a very clever clue. Thanks for the vote - interesting that you preferred the version with the typo!
