Sat. June. 23

He lives in Los Angleles, has a castle in Scotland, and, occasionally, sets foot on an American stage. Not that he's trying to "make it" here. Doesn't care, really. Just goes about his life, does his thing, finds humor in everything - dark and light. Billy Connolly is one of the funniest Scots you'll want to see. One thing, he hasn't drunk for 23 years so you can probably understand him. Another, he has general ideas of comedic bits, but they can veer off in many a direction. Sometimes, Connolly returns to home base; sometimes not. He never writes anything down. At 64, he's followed George Carlin's path in - well - not mellowing. Anger and caffeine are two prime movitators. And you can see where a young Eddie Izzard took a look at Connolly - arguably the world's most popular comic (if you take the US out of the equation) - and said, "Right, I could do that." Izzard and Connolly are part of a mutual admiration society. Conolly finishes his run at the A.R.T.'s Loeb Drama Center - though it's not an A.R.T. event -  Saturday June 23. We caught a show. Two hours of free-from riffing on everything from sex to vomit, religion to rituals, with the acknowledgement that, yes, he's a rather rich man, and a sharp streak of self-deprecation. There moments of tears-in-the-eyes humor. Especially good: Bits on dwafism, fatal illness, marching bands. Tickets: $55-$50. Show at 8 p.m. Oh, if you want more, we've got a pretty extensive and funny Q/A that ran recently in the Boston Phoenix - thephoenix.com,
