It sounds to me like they might have experimented with a sped up Freddie doing the high 'Galileo' bit before Roger recorded it, its during a 'quiet' moment on the track (probably headphone audio) so turn it up, but it sounds funny. Yes, I am bored.
Sounds unaltered to me. But yeah, he doesn't have Roger's extreme confidence in that range. Their huge choirs wouldn't have sounded half as good without Roger's amazing falsetto.
The ‘Galileo’ section was scored for three soloists: soprano and two basses (they overlap at one point). Soprano was recorded on Track 21 by Freddie and on Track 23 by Roger. Bass No 1 was recorded on Track 22 and Bass No 2 on Track 24, both by Freddie. The leak from Freddie’s headphones from Track No 24 shows that Fred had also recorded a very high part for ‘Galileo’, singing two octaves higher than the low one instead of a twelfth.
Wow, that does sound sped up. Quite obviously, too. Maybe it was an idea they tried, to perhaps provide more backing vocals. Or maybe it was to provide more definition to Freddie's falsetto part? Who knows.
That sounds like a character from "Lord of the Rings". Yup, pretty sure about it :-)
I think that the first Galileo is Freddie's, and the second sounds indeed like Roger. I'm only saying this based on the way each one says Galileo.
Freddie clearly says "Gali le i o".
