I don’t recall the background music at all, but Harold & Maude was a very good film! The movie was as odd as it was endearing.
Ruth Gordon played the same type of spry, bold and tangy sort of Lady as she did in Rosemary’s Baby.
Will admit, Ruth Gordon, was very good in "Rosemary's Baby", especially with the line to Mia Farrow, "Dear I"ve got to get to finish my Christmas shopping". A lot of irony there.
But "Harold and Maude", yuk, ewwww.
