David Bowie, Roxy Music: Rainbow Theatre, London

GOING TO THE Rainbow these days is definitely an outing, an excursion, something of a treat. Unfamiliarity breeds respect, and though the cheerful hippies who used to sell you hot dogs and guide you to your seat have been replaced by bored-looking usherettes, there's still that thrill as you wait for showtime. Mr. and Mrs. First Nighter... this is your life.
