I just returned from a road trip to see Graham Nash at the Birchmere in Alexandria, VA with one of my buddies. Two nights of sold out shows. He told a lot of cool stories about the songs he performed, he interacted with the audience, had a great band and played for one hour and 50 minutes without a break. Impressive feat for an 84 year old and still a strong voice in his sixth decade of singing. Closed his set with Teach Your Children and closed his encore with Suite Judy Blue Eyes.
He's got 18 more shows scheduled in September and October mostly in the Northeast and well worth it if you're close by.
