I've seen the Chieftains live, once. I got straight back home, and listened to this album, because it really does seem to encapsulate the whole experience of a Chieftains live performance. It really is like this album plays it.
There's the medleys, the guest spots, the Irish dancing, the whole lot. It's well worth a listen to if you're ever planning to go to a Chieftains performance, and it's probably well worth getting if you want to recapture the atmosphere of a performance if you've been to one before. About the only thing that could be better, aside from the real thing, of course, would be a DVD of it, watched on a big screen, with surround sound.
I love this album, it's one of my favourites. I swear, I've nearly worn the shiny off the CD by listening to it.
