Freddie Mercury and Montserrat Caballé Duet- Barcelona

I discovered this video last year when I became obsessed with Freddie Mercury after the movie Bohemian Rhapsody came out. I watched every Freddie Mercury video I could get my hands on.  I came across this one, a performance that is the result of a collaboration between two extraordinary artists-- the amazing Montserrat Caballé and the equally amazing Freddie Mercury.  They made an album together in 1987.  This is one of the songs from that album. Later, after his death, it was featured at the 1992 Summer Olympics, held in Barcelona, Spain.

I think the music, the artists and the performances speak for themselves. What do you think?
