Heard Richard Thompson on the radio this morning doing a cover of Britney Spears' "Oop, I Did it Again" with a great Nirvanaish arrangement for acoustic guitar and voice.

Even more intriguing was a few seconds of a troubadour-sounding arrangement of the same song that he has apparently been doing live.

The chord changes of "Oop, I Did it Again" are very medieval -- a structure that must have been unconsciously transmitted via the original Swedish songwriter, Max Martin. The transformation of this material was dramatic. I wish I could have heard a full version.
