The 81-year-old rock icon recently pulled out of two shows in a single week, raising concerns about his health. A representative said: "Doctors are pleased with his recovery, and Rod is doing very well and has returned to his normal daily activities. In a statement, Sir Rod said: "I’m already feeling better and very much on the mend. The latest health scare follows a respiratory infection and later laryngitis that forced the star to cancel a show in June. Just a week later, Sir Rod stopped mid-performance in Utah and was seen using an oxygen tank onstage after nearly passing out.
