TOP NOTCH PERFORMANCE . I saw Denver in concert in Ireland in April '97.I saw him a couple of times before that in the '90's. It was the last time I would see him in concert sadly. He played solo. It was amazing. I went out and bought this the very next week. Denver is in top form both musicially and vocally, as is his band. There are also some interesting monologues peppered throughout the concert where Denver shares his concerns about the environment and wildlife preservation. A great performance all round. RCA /SONY:If good quality sound and vision footage exists of 1970's ( I'm sure it does!)Denver concerts, please release it for the fans NOW
