The Infamous "Gimme Me A Call"

It's worth taking into consideration (which I suspect you already have, but still...) that Frederick's timbre was so hoarse that night, judging by that audio. It was definitely Frederick, not Roger, singing that line.

I beg to differ: comparing it to his voice a few seconds later, it's clear to me that Roger just joined in for the title drop. That's also consistent with the second iteration of the chorus (near the end), in which Roger, again, stays quiet while Frederick sings 'just give me a call'.

Besides being a brilliant musician, he was - at that time - a self-indulgent coke-snorting pleasure-seeking hedonist, so taking care of his voice wasn't by any means his top priority. Had it been, they would've cancelled the concert.


Yeah, but that doesn't exclude the possibility of nailing one note accurately, which he evidently did.

Because it sounds like him, it's got the same timbre, panning, volume and tone as his voice throughout the rest of that performance, it doesn't sound like Roger, John or Brian, it's consistent with the evidence we've got from other renditions of that particular track during that tour. Frederick had a horrible night, but he managed to hit some notes quite accurately, including that one.

Because it is Freddie, that's why. Roger never sang on that line, and it sounds nothing like Roger anyway.

If roger sang it his voice would be far more distant, listen to a part Roger did sing "Call me Mr Fahrenheit, traveling at the speed of light".

The other possibility is that for a brief moment Roger used Freddies voice.
