A dear friend once said to me out of the blue, “Today it will have been forty years since the last time I vomited,” and I said to her, “How do you celebrate an anniversary like that?” It was a witty moment, one of many in our friendship, and if we’d only collected them all, we could sit down and write a Cole Porter musical, but we didn’t and anyway Cole Porter isn’t so hip anymore and we’re busy doing other things.I, for one, have been on a tour doing a one-man show and having a great time until last week in Boothbay Harbor, Maine, after a dinner of six oysters on the half shell, clam chowder, and a lobster roll, I awoke at 4 a.m.
