See enough Willie Nelson concerts, say at least a half-dozen, and you'll really start focusing on the little things. Sure, the set list may not change much from show to show, if at all, but each one that comes around makes the subtle variations applied by Willie and family stand out that much more.
Plus, these are songs like "Whiskey River," "On the Road Again" and "Georgia On My Mind" we're talking about, so it's not wise to look a gift horse like that too closely in the mouth anyway.
Tuesday night at a sold-out House of Blues, the biggest question going in was whether the atmosphere would be as fragrant as the previous evening's Method Man/Redman/B-Real blunt brigade, and Willie's fans more than held their own. There was some pretty powerful herb being passed around for sure.
