Found a copy of “Love At First Bite” , released in April 1979, at my favorite Book/CD/DVD store, Goodwillbooks.com. Arrived this week.
It was coincident with my surrender to a legacy AM/FM/CD/DVD/BluRay 5.1 entertainment sound system (being donated to Dorcas Ministries Thrift Shop) that had me doing 20 minutes of remote control Kabuki to watch a movie with a paired Bluetooth headset (considerate of my apt. neighbors).

My 2 year old TV has no audio out except it’s speakers and Bluetooth. And it’s own take of who controls what. A $65 DVD player fixed me up. The last lines in the script are my favorite:
Cindy Sondheim: Oh, this isn’t so hard. I think I’m going to love immortality!
Count Dracula: There is one small disadvantage. We can only live by night.
Cindy Sondheim: Oh, that’s all right with me. I mean, I could never really get my shit together till 7:00 PM, anyway.
