I downloaded the full FLAC version a few months back and noticed today that there is a weird sound at the beginning of Ogre Battle and another strange sound like a "chiggachiggagaga" sound right before the medley starts. Almost like a whisper. Anyone else notice this? I don't recall hearing this on another version of the concert that I have. I am only on Killer Queen and wonder if this exists throughout the entire bootleg of it.
It's just a sound effect that the Swedisch Radio station felt like including. It doesn't happen throughout the rest of the concert though apart from the intro and outro when it was broadcasted.
If you got the complete boradcast version it will also include that intro and outro.
