The highlight of our 2000 tour with David Kilgour, Mac McCaughan and Lambchop was the four shows in three days at San Francisco’s Great American Music Hall, a run that started 14 years ago today.   By now, Lambchop have pretty much an open invitation to join in on the second encore, which on this night means covers by the MC5 and Devo, and a concluding ba-da-da-da chorus of “Ripple.”  Eight years earlier we weren’t having quite so much fun.  I understand how working at a rock club can make one fear for their hearing, so I hate to be judgmental.  Nevertheless I don’t think it set a good tone for our date at Northampton’s Iron Horse when the stage crew put in ear plugs . . . for our load-in.   Suffice to say, there was no second encore.
