The monarch's own musical tastes are a mystery, and the Press Association news agency reported she brought a pair of earplugs to a similar concert a decade ago. According to The Guardian newspaper, the only song the queen has ever been known to request is Some Enchanted Evening from the Rodgers and Hammerstein musical South Pacific.
"I don't think she's a big pop music fan," said Elton John, who paid tribute to the monarch's constancy.
"She's not trendy, she doesn't follow any fads," John told the BBC. "She's stoic, she's brilliant, she's wise, she's funny, and we're all really happy to be here."
