While taking a shower this morning, I suddenly heard a banging in the water pipes. The noise had the distinct ring of a $200+ plumbing job. So I was relieved when I emerged from the bathroom to find that the source of the racket was Dominic, practicing on his bodhran drum. Dominic was proud of his percussion accompaniment to a Celtic air. Would he be amused if I told him that it sounded like Celtic air-in-the-pipes?
