Maybe you'd better watch it again Amigo with a few stouts as a preamble. What was it originally rated at in the UK, I don't think you may have seen the original uncut film.
Here this is from the IMDb on its certification:BlindmanCertification: Finland:(Banned) (1972) / Sweden:(Banned) / UK:X / USA:R / Canada:18+ (Quebec) / Canada:R (Ontario) Wow, banned in Finland & Sweden, rated "X" in the UK, its pretty tame stuff, lol. How did you get in the theater back then Belkin?, lol.
