Well, my year of retro-rock concerts has come to an end. I attended a terrific Crosby, Stills and Nash concert which proved two things: 1) They can still pack them in, and 2) They can still sing.  This was actually my third trip to one of their shows in the last 6 years.  Two of them were just Crosby, Stills and Nash,  and the other  was Crosby, Stills, Nash and Young.  This was the best. For some reason, these guys have become amazingly energized.  They did a 2 1/2 hour concert with a 15-minute break and their harmonies were, as always, memorable.  They started with the song Carry On, and then went on a fantastic journey through their catalogue. Of course, they can't do everything.   Among the missing numbers were Ohio, Woodstock, and Marrakesh Express.  They threw in a couple of Buffalo Springfield songs, and a couple of Stills solo numbers, including "Love the One Your With.". I wish Nash would have given us a song or two from his days with The Hollies.   David Crosby's voice was strong, in fact stronger than Ive ever heard it.  There was however one hilarious moment in his signature song "Almost Cut My Hair".  Crosby drew a blank about 45 seconds into the song and sang the phrase: "I forgot the words" and sang that line right in tune.  The two others immediately rescued him and he got back into it.  Just a senior moment I guess.   It blew my mind though that this was the second straight show I attended where the acts had performed at Woodstock!  First Joe Cocker and now C.S.& N.   So I have tickets for two more shows this year, both in December, Green Day, whom I've never seen live and Springsteen, whom I've seen 19 times.  It's never enough.
