That’s my man Paul Kandel hitting a D5.
Rumors are that he had to split the recording into two sessions. The first was for the rest of the song–the second was to come back for the D5.
Here’s a recent live recording of it with David Lakshøj Hansen performing lead vocals. I leave it to you to say whether he did it better
In all seriousness, my gold standard for tenors is Luciana Pavarotti’s C5 at the end of the famous “Nessun Dorma.” Here’s his final performance of the song before his death. He is lip syncing so as to avoid any possible hiccup in what he knew would be his final performance, but the emotion on his face is real. He knew what was about to come.
I also followed Jame Labrie from Dream Theater for a long time for his sort of operatic sound, though he’s of course relied more on a mixed voice and falsetto as he’s gotten up there in his years. Here he is hitting an F#5 in “Innocence Faded” (after the “wearing apathetic display” lyrics around 2:10) way back in the 90s vs 12 years ago for the Score concern vs how he sounds singing the same passage today.
