I know there are some intresting stuff on youtube regarding this song.
From the recording sessions, interviews and so on.
I think one of Queens trademarks (as mentioned) was the Massivly dubbed Choirs and The same went with the Guitars.
I think Freddie was the main part to why queens choirs sound so good, he was very into it.
Listen to the backing vox on Love of My life, and you can easily hear that he`s classicly trained, or at least with lots of knowlegde on the matter.
He also did most of the voices himself, Roger the the highest stuff, but other than that freddie did the most overdubs.
I remember when I first got the album Night at the opera, it was long after I heard Bohemian Rhapsody to death on the Best of album.
One of the songs that really caught my attention on that album was the tune The Prophet's Song.
After a while into that tune Freddie starts on an acapella piece wich lasts for a minute or so.
It sounds great, really great.
I remember playing this for a girlfriend of mine and she was no musican but I`ll never forget what she said, when I played her the acapella piece.
His voice is just music alone, he`s just got that special voice.
Very few things I`ve heard said about Freddie Mercury (Farouk Bulsara), have been more accurate.
Btw did either of you know that Freddie was a Boxer at young age, apparntly a quite good one
