As the world mourns the loss of David Bowie today, one of the most influential and iconic musicians of our time, tributes are pouring in from across the world.

Any time we lose a talented musician though, it's interesting to think about the old "rock band in Heaven", and how Bowie may now be reunited with one of the greatest rock singers ever - Queen's Freddie Mercury.

Of course, David Bowie and Queen had a smash hit in 1981 with "Under Pressure". Just in case you needed a reminder of just how talented both singers were, here's the song with all of the instruments and background vocals removed.

Bowie and Freddie a cappella. Enjoy!
