I found this gem on Youtube that goes back to my high school days. Poco was a very successful country-rock band from the mid-70's, and quickly got diminished by the likes of the Eagles, and soon after punk rock and new wave music. I was surprised to see that these guys still perform together 35 years later. I have the vinyl album where these songs were originally released. Here Poco performing "Heart of the Night" in 2008. The old hippies have gotten older, grayer, and less hair, but sound great.
