I've heard this effect on some Later Years material (notably during the end of Venice '89 and spotted throughout the Torino 94 soundboard). I have some questions about it:
1. What is the best source of this sound effect?
2. What are they saying?
At first I thought it was from the end of Fearless, but it doesn't match that at all, since it's just a repeated crowd chant.
Any help is appreciated.
