It’s only fitting that the lead guitarist of the rock band Queen would be honored by the king.

Legendary guitarist Brain May will now be known as Sir Brian. On Tuesday, the founding member of Queen received Knighthood from King Charles III in a ceremony at Buckingham Palace, per CNN.

May received the title of Knight Bachelor for his services to music and charity, reports the BBC.

Queen congratulated their guitarist in a Twitter post: “Arise Sir Brian May,” the band wrote. “Brian’s investiture as a Knight of The Realm took place today at Buckingham Palace. The knighthood was presented to Brian by His Royal Highness, King Charles. Many congratulations, Sir Brian!”

May is not just a rock icon — he’s also an astrophysicist. In 2007, he received his PhD in astrophysics from Imperial College London. May took a break from his studies in the ‘70s to focus on the band, per CNN.

He is also an advocate for animal rights and a critic of hunting. In 2010, he formed Save Me Trust, an organization which campaigns against fox hunting and badger culling.

May famously performed “God Save the Queen” from the palace roof during the celebration of Queen Elizabeth II’s Golden Jubilee in 2002. Two decades later, he performed with Queen at Elizabeth’s Platinum Jubilee Concert.

What does it take to get knighted?

Anyone can be nominated for knighthood or damehood as long as they meet the king’s criteria, according to Awards Intelligence. Knighthood and damehood can be given to an individual for all types of achievement. Typically, nominated persons have made a major contribution on a national or international level.

An award will be given if the nominee’s “work and achievements will be viewed as an inspiration to others; and they may have influenced their peers, industry or the nation through their sustained and outstanding commitment to their chosen area.”
