Queenie Watts!

That's the woman who belts out a tradjazzed-up version of gorblimeyguvnor cockney music hall standard “Goodbye Dolly Grey” (a Boer War era ditty) in the pub ruckus scene in Alfie (on TV for the umpteenth time earlier this week)

surely ripe for insertion into one canon or other of Anglo-antiquarian esoterica...

googling her name I came across a reference to her being John Entwhistle's mum, which can't be right, surely? but oddly would fit into some kind of trans-generational Brits-projecting-towards-Black-America continuum...

on the white-on-black theme: almost too obvious to say but Flight of the Concords = Hot Chip with non-musical interludes

and still on theme: seemingly shown on American TV every week at the moment
The Blues Brothers. I imagine this was regarded by most rock critics at the time as some kind of travesty of soul music, I'm sure the likes of Dave Marsh say would probably have fulminated against it.... nowadays it seems faintly poignant on some level, Belushi and Akroyd's earnest reverence for Sixties soul not far beneath the parodic surface... c.f. Flight of the Conchords, these schlumpy white guys who want to become the elegant frenzy of the black performers they venerate but can't make it so they make a joke of themselves (while still pulling off some under the goofiness actually quite slick and physically impressive moves)
i have never managed to make watch more than 1/4 of it--usually a chunk in the middle--before giving up though... there's a bit that portrays country music fans as Nazi thugs more or less which you could never get away with now...
