Audience response back in the day?

I think they just placed mics close to the audience and turned the volume up. The bootleg of the same show is from a soundboard so you never really hear the crowd anyway.

I think they did the same on Truth or Dare (Madonna doco) I've seen bootlegs where the crowd go wild but on all the pro shot versions you can't hear them, except on the concert footage captured on TOD.

Does anyone with techinical knowledge know if I am right.
