From the poster:
We love Queen and Freddie Mercury, so we’ve edited 4 concert films including a rare recording session of “We Are The Champions” and synced them all up to the isolated vocals in honor of the late, great, Freddie Mercury. This video showcases his presence and consistency as the ultimate stage man. RIP Freddie. You are a rock god.
Agreed. Worth listening to, worth watching. Loved every minute of it.
