Fans of John Denver are gathering in Aspen to celebrate his life. Denver died 20 years ago this week. His song about Colorado, "Rocky Mountain High," was a hit and eventually became the state's second song. Today, Colorado Matters follows John Denver’s rise to stardom and the frustration felt by some Coloradans that his song led too many people to come to the state. We’ll also meet Denver’s longtime bodyguard and meditation instructor.
