As the years went by, and people's attitudes were changing, his sketches and songs were very much watered down compared to his wacky original material.
I don't know whether, on HBO, that you saw the really raunchy stuff, or whether you caught the latter watered down stages of his career.
A typical sketch, and there'd be many during a show, would involve, for instance, secretaries bending over in the office to pick up Benny's pen, which he had "accidentally" dropped. The secretary, in good old Benny Hill style would be wearing stockings and suspenders and the viewer would get a real eyeful! Policewomen and maids featured a lot too, all eventually either bending over or flashing ample cleavage, and then being chased around to the classic Benny Hill tune.
His songs were quite raunchy too, peppered with double entendre. One such song, "Ernie (he drove the fastest milkcart in the west)", reached No1 in the UK singles charts, lol. It was probably released in the US too.
As a 10 year old lad I thought it was all brilliant, it was almost like mild porn to me, lol.
