Kinks brothers reunite. A lark or a sign from Ray and Dave Davies?

Poor guys. For years, nearly any interview they do has to inevitably wind up to the big R question. Have you talked to Ray? Is Dave willing to play with the drummer? A tour? A new record? A film? Then here comes Ray, in his pea coat and clutching a bottle of water, showing up Friday night at younger brother Dave's show at Islington Assembly Hall in London and proceeding to sing the song that may have invented punk rock, 1964's "You Really Got Me."
