Paxton has been a significant name in the folk music world for 50 years now and he performed a mix of old and new. That included his first hit ("The Marvelous Toy") and several of his best known songs ("Bottle of Wine," "Ramblin' Boy," "The Last Thing on My Mind"). I was amused by his inclusion of a one verse parody version of the latter, found on the internet. Somewhat surprisingly, the only other satiric piece he performed was "I'm Changing My Name to Fannie Mae." That song is a minor rewrite of "I'm Changing My Name to Chrysler." To quote Tom Lehrer, "it don't matter if you put a coupla extra syllables into a line" but the poor scansion does bother me. So do some weak rhymes in other songs and a few unnecessarily repetitive lyrics. There are certain genres where fans can be excessively forgiving and, alas, folk music is one.
There were some performance weaknesses too. Paxton has always been a better songwriter than a singer and he had trouble keeping his volume consistent at times. He was still energetic and did get the audience singing along fairly frequently. But I noticed his somewhat limited range more than I might have otherwise. (Of course, the limited range is part of what has made him a songwriting success. His songs tend not to be very hard for other people to sing.) I should also note that he was accompanied by Robin Bullock, playing guitar, cittern, and mandolin. In general, I thought the accompaniment was effective and, in a few cases, it overshadowed the songs themselves.
But concerts by musical legends have as much to do with nostalgia as with the actual performance. Oddly, the age of a song has little to do with the feelings of nostalgia it brings up. My personal reveries were focused on "Central Square" (which is, I think, fairly recent and unrecorded), "Comedians and Angels" (which is lyrically weak, alas) and "The Bravest" (about 9/11). Those moments made the concert worth going to, but I don't feel any great desire to see Paxton perform over and over.
