I did have a recorded TV broadcast on vhs that I used to watch everyday when I was like 4 years old. My first purchased copy of the SW trilogy was the '97 SE's and upon watching them for the first time it really stuck out in my mind that Luke made the throw first time around and him and Leia made the swing etc.
Whether I remembered incorrectly or this was edited for the SE I did not know, but it was soon forgetton about as I watched the SE a bunch of times and it became normal for me seeing Luke make the throw first time.
Sadly I no longer have that vhs tape of the tv broadcast. Actually, from my childhood I had two recordings of different tv broadcasts of SW. which one I am remembering or think I am remembering I don't know.
All this is probably my mind playing tricks on me, because as a kid I could have sworn that Luke shot the controls to extend the bridge by accident as he nearly runs over the edge. But we all know he does it on purpose a few moments later to stop the stormtrooper coming through the door.
I guess its safe to say kids don't get everything that happens in a movie, well at least I didn't. Though it didn't stop me from enjoying it any less.
