John Mayer - "Waiting on the World to Change"

During the height of John Mayer's reign, he scored a #1 Adult Contemporary hit with "Waiting on the World to Change".  At the time, it was Mayer's first social commentary about the political scene from that era (2006).  Over the past handful of years, John Mayer has been MIA.  Should someone do a well-being check on him?
