8. 'The Show Must Go On'
Freddie Mercury knew his body was rapidly failing him when Queen began work on their 1991 LP Innuendo. He was determined to complete one final masterpiece, and Brian May wrote "The Show Must Go On" about his unbelievable drive. It ends the album on a note of defiance and hope, and Mercury has rarely delivered stronger vocals. They weren't able to perform live to support the disc and in videos from the time it's alarmingly clear just how frail the singer had become. He died nine months after the album came out.
