I was watching a film called "The Green Man" from 1956. There was a scene where a trio (piano, violin and double bass I think) played a classical song which I knew I had heard from an old computer game - I just don't know which one. I don't even know the name of the music - I've tried on YouTube but I can't find it. A lot of old computer games (early 80's) were made by guys in bedrooms so they used classical music as it was free from copyright. Every time I hear "Funeral March of a Marionette" (the theme from "Alfred Hitchcock Presents" - you'll know it when you hear it) I always think of a game called "Seamus 2" :)
