Holy hell, was that awesome. We were in the 12th row, and the Moore Theatre is a rather small one, so it was a cozy feeling all around. During their second encore, they quieted the audience down, and sang "Old Brown's Daughter", a capella, completely unwired. No mics or anything. It was utterly fantastic.
Apart from the two encores, they played two sets - the first one was filled with "traditional" songs, many of their sea chanteys and such, and the second was mostly their more poppish type stuff.
It was particularly great, considering I only found out that they were playing on Friday afternoon. Yay.
Next up is Ben Folds, in about three weeks. Should be awesome.
