King Charles Knights Brian May, of the rock band Queen, at Buckingham Palace

King Charles III knighted Brian May, co-founder of rock band Queen, during an investiture ceremony at Buckingham Palace on Tuesday, the royal family announced. In addition to his fame as a rock guitarist, May is also an astrophysicist.

May, now officially known as Sir Brian May, was made a Knight Bachelor for his services to music and charity. Saxophonist YolanDa Brown was also honored at Tuesday’s ceremony.

Anita Dobson, May’s wife, was also present. On Instagram, May shared a photo showing King Charles putting a sword on his shoulder.

“No words,” May wrote.

The rocker made it onto King Charles’ New Year’s Honors list in the UK at the end of 2022. The investiture ceremony, which involves someone awarded an honor receiving it in person from a member of the royal family, took place on Tuesday.

“I will do my best to be worthy,” May said after being named to the list.

Tuesday was not May’s first trip to Buckingham Palace. In 2002, he performed “God Save the Queen” from the palace roof during a celebration of Queen Elizabeth II’s Golden Jubilee. He also attended a music party at the palace in 2005. That same year May was made a Commander of the Order of the British Empire.
