Don't expect a musty museum tour, however. While we get plenty of the familiar perennials ("Basin Street Blues," "Tiger Rag," and, of course, "When the Saints Go Marching In"), the musicians are not totally mired in the past. Indeed, the highlight of the 70-minute program (which includes some history of Preservation Hall as well as interviews) is a lengthy version of "St. Louis Blues," with extended solos by all the players, walking bass, and swing tempo--all touches that didn't come along until years after New Orleans jazz was first played. But those are the finer points. The accent here is on letting the good times roll. The musicians are clearly enjoying themselves. So's the audience--and so will you. Okay, so it's not deep. But it sure is fun. --Sam Graham
