Of the handful of tracks like this that I have on hand, where there is something very subtle in the mix, this one is the easiest to hear. Though I must admit that I was surprised to find that it is evident even from the Youtube clip.
rbbert is correct in that the section at 5:40 is more difficult and part of the fun (for me at least) was to see how many people picked up on that one as well.
For those playing along, jep123's guess is in the neighborhood but not correct......
Also, now that there has been something concrete suggested, it would be interesting to see how it influences what other people hear just through the power of suggestion.
I have a friend who insists that he knows what some of the Ewoks are saying in "Return of the Jedi". Now, I know he's pretty much off his rocker on this. But damned if I don't "hear" exactly what he claims they are saying every time I watch that movie now! I think it's funny. But I also find it very fascinating.
Anyway....... Merry Christmas everyone!
Play on!
