Great Concerts! Just Listened to Nils Lofgren, brings back memories. But, in regard to "Keith Don't Go!" the reviewer states that the song was written about Keith threatening to leave the Stones. As I recall, the song was about Keith's drug bust in Canada in the seventies, and advising him not to risk returning to Toronto for the trial, as he was facing a possible prison sentence. The lyrics tell the story clearly: "Don't nail yourself to that cross!" As far as Nils' talents, the reviewer is dead on. Beautifully melodic song writing, and a very distinct guitar style, one of all time favorites.
