Winterbourne House: HDN locale.

It goes without saying, so I won't, and this is certainly one of them. Iconic photos of the manic-era Fabs, as per above left, are all about running, jumping, waving, posing with soft-toys, and crawling on hand and knee from Dutch bordello at 6 in the morning (errr..has anyone actually seen that photo?

HDN parodied much of this in fine post-modern style, o' course, and never more so than in the famous scene where Ver Fabs are chased up a dead end, only to etc.. The intrepid trio ('oo else?) of Lewisohn, Schreuders and Smith tracked down the locale, a tricky job as the cul-de-sac in question is long gone.
However, on-location photos reveal a bit more detail, including Winterbourne House in Notting Hill Gate, still very much there:
