Great question! I'd think to say no right off the bat. However, it was 1979 when it was shot so in my opinion I think it's possible that it could be. However, I'd bet against that being the deal.
Here's a question: who's the chic that skates up to Man and Deeeeeeeeeee Wayne ("Red") Mendoza, gives them a flyer to the massage parlor and asks if they have any "blow"? Character or real actress' name? She's cute, but I have no clue who that was.....
