Queen's Brian May Recovering From Surgery

Queen guitarist Brian May is recovering in a U.K. hospital following surgery on one of his calf muscles.

The news was revealed by May himself, who waited until after he went under the knife to share the story Monday on Instagram. He wrote, "I’m done! After a snip to my calf muscle, I’m feeling good! The theory is that it will release the excess tension in my Achilles’ tendon and get me out of a painful heel situation I’ve been in for many months."

Queen's upcoming world tour, which will feature Adam Lambert on lead vocals, is expected to get underway in mid-January.
