Query: Which Queen member retired in 1997?
Context: It was released as a bonus track on the Queen Rocks compilation album later that year. In January 1997, Queen performed "The Show Must Go On" live with Elton John and the Béjart Ballet in Paris on a night Mercury was remembered, and it marked the last performance and public appearance of John Deacon, who chose to retire. The Paris concert was only the second time Queen had played live since Mercury's death, prompting Elton John to urge them to perform again.
