I attended the Mark Twain Prize award at Kennedy Center on Monday. Do not expect too much Twain in the show when it is broadcast next month. Other than a few comments and a quip from Whoopi Goldberg on "Hollywood Squares" most of the Twain was in the name, the statuette, and the backdrop. Alan King apparently was given the make-this-relevant-to-Twain job. He came onstage carrying a book and explained that he was there because he was old enough to know Twain. He then recounted a fictional evening, sitting on the porch overlooking the river with Sam, swapping lies and watching Whoopi work in the fields. With that tasteful introduction, King read a few Twain aphorisms to diminishing applause, then disparagingly gave up on the material and turned to introduce a segment of the Ken Burns film. Similar aphorisms on the film got better audience response and King seemed surprised. Perhaps it was King's delivery. He ain't no Hal Holbrook. I believe that three or four of the people doing appreciations of Whoopi G oldberg were people who are on Hollywood Squares. A group called Three Mo' Tenors provided a musical lift, and there were two more Sammy Davis impersonations than I have seen in a very long time. Dennis Kelly San Francisco
