For those asking about the Exorcist musice... its simple. In the 1970's, producers 'borrowed' copyrighted music from Hollywood films... without permission of course... as they did not create original music themselves... Original music in porn really didn’t start til the 1980's...Lawsuits by studios would've been a waste of time...as who were they gonna sue? Most names of producers, directors etc were all faked anyway... most porn in the 1970's was financed by the Mob... mostly in New York...
I know the mousy one in the green blouse is Kim Pope, but in this she so reminds me of the late Georgia Engel, the actress who played Mary's friend/Ted Baxter's girlfriend, Georgette, on The Mary Tyler Moore Show.
