A few years later, there were no original members left in the trio, so the name became Denver, Boise, and Johnson. Michael Johnson later went on to have a few pop hits in the 1980s, including "Bluer than Blue,) which is very much soft rock AC radio cheese - but I always loved it anyway. He sings the catchy melody convincingly:
Denver and the original trio performed a few times together in 1987. The Chad Mitchell trio still performs. Based in Seattle, they played for President Obama in DC last year. They were first to record "Blowing in the Wind," but their label objected to the lyrics, so Peter Paul & Mary's version was released first and the rest is history.
