Most likely people under age 40 have no idea who John Denver was. He had a string of pop hits. Then he died in a airplane crash in some sort of experimental plane? He might have been a goofy granola-eating liberal but he did write some pretty good songs in the "folk-rock" style back in the 1970s. His first big success was writing a song called "Leaving On A Jet Plane" which was a big hit for Peter, Paul & Mary, another group of granola eating liberals. His real life name was Henry John Deutschendorf Jr. Yikes, that's a mouthful....
