I measured the long and high "Bed of nails" part.
If i remember correctly it was D#4 in Sao Paulo (will measure again to see if i remember correctly)

In Las vegas 2018 it was G#4 (few notes higher than D#4)

Live Bor every short "Bed of nails" is G#4 and studio it's A4 (half note higher than G#4.)

It's a very bad sign now if he's sounding thinner on the same note IF he's as loud as before on the same note.
