At first glance it seems the person singing in this clip is Amy Winehouse - then you realise they're far too sober and singing far too well, and it becomes clear it's just her pal.
Amy bops along on bass though - in her bra and knicks knacks and with a fag on the go. The guitar's bigger than her. Amy-still Declining-by-the-minute-house. When, (make that ever) will she be in the papers for good music again?
