My parent's first date was to see Star Wars, so I didn't get to see that.
Had all the records and storybooks, so my memories are a little muddled, but I believe I first saw Star Wars on HBO once or twice when I was maybe 6, so I never had as strong a memory of it until we got in on VHS later in childhood.
We had a taped copy of ESB off of HBO that my brothers and sisters and I watched until it shredded.
Have no clue when I first saw Jedi. Dad says he took me to the theater, but I was four so I don't recall.
