I don't remember exactly either, but I know I watched it off a VHS tape that was taped from TV. I watched it daily during the summer one year when I was a kid.
When I saw Empire, I remember being utterly enthralled by the Yoda training scenes and everything to do with the Force. That was when I realized my favorite characters were Luke and Yoda. Everyone else always wanted to be Han, so it was kinda cool that I could be Luke and have my trusty lightsaber.
