The first 30 seconds, when the audience is in view - Visually, they look like they are clapping on 2&4.
Sound wise, I can't hear any clapping.
To me there seems to be a sound delay when the audience is singing, possibly, because of the distance they are from the recording mic.
It seems to be right next to the Bass and Drums.
I am not sure why I am droning on, I couldn't careless what the audience (or AC/DC for that matter) are singing or clapping along to.
Just responding to a post (PaulGibsonBass).
I think he is great. (Although there are better versions of that tune, with him playing, that are knocking around).
Carry on.
