Incredibly someone (not me) has managed to trace the location used for the exterior scenes of the early MM film ‘Betrayed’. Goodness knows how, given that you see it only fleetingly in the film and the location has changed quite a bit since then. It is in Amsterdam, and when John Lindsay made the film was obviously some kind of a pub or bistro (as in the context of the film it is where the men go to down a few pints) but is now ‘San Jovany’ an Italian restaurant. Although all these years later they still have a sign plugging Heineken beer outside!! It you want to look it up on Google earth the street address is “San Jovany, Westermarkt 23, Amsterdam, Nederland”.
