Andy Kim, the co-writer of “Sugar, Sugar” and the Neil Diamond of Canada, was part of an eclectic celebrity cast coaxed together by music producer Hal Willner a couple of weeks ago to mark the 60th anniversary of the first reading of Allen Ginsberg’s “Howl.” Kim—whose big solo hit was “Rock Me Gently” and who also made records as Baron Longfellow—was not singled out in news accounts of the show, though there are photographs of him sharing a mic with Kevin Drew (key collaborator on the new Andy Kim album It’s Decided), Courtney Love and Damon Fox. The event was a benefit for the David Lynch Foundation. Other performers included Nick Cave, Van Dyke Parks, Tim Robbins, Lucinda Williams, Beth Orton, Macy Gray, Amy Poehler, Fred Armisen, Chris Parnell, Will Forte, Davendra Banhart, Peaches, Petra Haden and Chloe Webb.
