Just one more rah-rah for the home team. Broadway handed the Tony for Best Musical to Memphis on Sunday. But if you were a fan of the North Shore Music Theatre (in its former incarnation, under Jon Kimbell) you saw Memphis . . . wait for it . . . seven years ago, in 2003, when it was a world premiere up in Beverly. It's nice to know, of course, that New York does eventually catch up to the Boston suburbs - but needless to say, it will cost you a lot more to see Memphis now than it did then!
