Everyone's got one or two, a film you used to love as a kid but have forgotten until you suddenly remember it and spend ages trying to find out what it's called so that you can find it on DVD if you're lucky as it's not seemingly available anywhere.
Mine's Rock & Rule which is like a cartoon from the 80's about mutant rockers. When I found a copy after ages looking for it I was ecstatic...and then slightly disappointed when I watched it as it wasn't as good as I remembered. Nostalgia's a bitter bitch, I still quite liked it though but the magic of it was destroyed utterly
I used to love this song, it was from the film. I literally used to rewind the video and watch it multiple times.
