This would be an amazing song anyway...but given the circumstances (Freddie Mercury at his worst physically, nearing death) and the appropriateness...it makes it even more of a tear jerker. Was filmed in black and white to disguise Mercury's bad health. Recently saw a documentary about Queen, and without the black and white, even with makeup he looked frail.
Also, I think he's saying goodbye and "I love you" to everyone when he looks into the camera at the end.
