Continuity mistake: During the "Another one bites the dust" scene, Freddie is given a sheet, which he holds with his left hand, beer in his right. A shot later the beer is gone and the sheet has swapped hands. Then a shot later the bottle reappears in his right hand. He never gives it or has it given back. (01:12:55)
Suggested correction: Freddie drops the lyrics sheet after shoving it in Roger's face - he holding his beer in his right hand. Freddie gives the beer to Roger and when the camera moves to a close up of John's hand's playing the bass, Freddie crosses in front of John and picks up a new sheet from the table where Brian is sitting. The bottle never reappears in Freddie's hand.
You're basing your correction on a moment that occurs minutes later in the scene. And the table is 3 meters away. He couldn't have left the bottle anywhere.
