AUTO TUNED? - Queen - Another One Bites The Dust (Live at the Montreal Forum, 1981 Remastered) 

There wouldn’t be much difference, it’s overdubbed not really pitch corrected, and those overdubs were done for the original release back in 1982. There’s no circulating recording of what the vocals really sounded like on that particular night besides what you can hear leaking into the surround channel on the 2001 release, closest you get is a recording of the show from the night before (which was a better performance of this song anyway)
