When it comes to R&B, Prince Philip has shown that he is more Rule Britannia than Rhythm and Blues.

The 91-year-old, who has set the royal standard in gaffes over the years, could be seen sticking his fingers in his ears during Alicia Keys' performance at the Royal Variety Show, the Evening Standard reports.

Other performers at the Royal Albert Hall included Rod Stewart, One Direction and Girls Aloud. When asked who he and the Queen thought were best he said: “All of them.. but to be honest, we’re both stone deaf.”
