Jim and I have been fans for a while of the Ukulele Orchestra of Great Britain, chiefly because of their amazing version of Shaft - though their Teen Spirit is also pretty fine.)
Last night we discovered their version of Wuthering Heights and I had to get up and play it again (several times) when I couldn't sleep. Now I have it on continuous loop in my brain.
They're not for everybody, but hey - we once drove down to a seaside dive in the middle of a week to see Those Darn Accordians play live, so what can I say.
If you do like this, I highly recommend trying their Life On Mars
