World-renowned British singer Elton John has been made a Companion of Honor by Prince Charles at Windsor Castle on Wednesday. John, 74, received the prestigious honor, an award restricted to the sovereign and a maximum of 65 members, in recognition of a music career lasting more than five decades and his charity work centered on AIDS.

The musician, who last month scored his first number one in 16 years with his Dua Lipa collaboration "Cold Heart (PNAU remix)," joins the likes of artist David Hockney, actress Judi Dench, musician Paul McCartney and author J.K. Rowling in the order.

One of the best-selling artists of all time, with hits such as "Goodbye Yellow Brick Road," "Rocket Man" and "Your Song," John was knighted by Queen Elizabeth in 1998.

John, accompanied by his husband David Furnish at the ceremony, walked with the aid of a cane. In September he announced his European tour would be delayed due to hip problems.

John has raised millions of pounds for the fight against AIDs, including establishing the Elton John AIDS Foundation in the 1990s.
