'California Girls', led by Simms, has been in my head all day. Here's the band doing it live in LA earlier this year. It seems oddly appropriate that the Simms is off-camera for most of the song (though she drifts into view towards the end).
For those who think that's all a bit folky, the other tune I've been hitting today is the cracker below, which brings back all sorts of memories of growing up in East Dorset's Colehill projects. Compton Acres, where it's at, yo. Anyway: it's officially impossible to beat the coolness of "Freeze. At ease. Now let me drop some more of them keys." Greatest hip hop riff ever?
The latter contains a ton of swearing, by the way. Oops, too late.
