For a lifelong fan, this concert's principals were Judy's singing, Stephen's guitar playing, and the songs. All were there in abundance. Close your eyes and listen to Judy Collins' voice which, at 80, sounds like she is 20! Her pure tones and incredible range haven't aged a day. And Stephen Stills has long been my favorite guitarist. As on the Stills/Collins album, he played as well, if not better, than I've ever heard him. Although his solo voice is not what it was, singing with Ms. Collins unquestionably raises his game. Song highlights were "Helplessly Hoping", "Houses", "Handle With Care", "Bluebird", "For What It's Worth", "Who Knows Where the Time Goes", and Judy's astounding a Capella rendition of a song (unknown to me) about mothers and children, which was especially relevant and poignant. The final encore was, appropriately, the final two sections of "Suite: Judy Blue Eyes." Fifty years in, Stills and Collins are still a good fit. Long may they run!
