When Freddie is in his pale blue outfit, right before Brian speaks, you hear something being said and see Freddie's mouth move. I think it was Freddie because he was a bit far from the microphone.
I know John Deacon leans forward to say thanks right before Freddie, but typically - you can't hear it. Hahahah, even at awards ceremonies he can't win.
Right before Brian talks, Freddie says something. I think he is saying it to Brian, as if saying "go talk" or something.
You CAN hear it. It's not loud, quiet, but you CAN hear it.
