A funny thing happened at Mass, and in some vague way, I sense there is a parable in it.
The celebrant murdered the Alleluia, and then went on to attack, I mean, "intone," the Sanctus (Holy, Holy, Holy). The melody was somewhat familiar, so as soon as I perceived which version he was aiming at, I turned on the volume, in order to support the assembly in singing it acappella. Unfortunately, Father had changed key three times by the fourth word, and he had the mike. I kept bravely trying, wincing at the resulting chord (it was an augmented, demented--oops, diminished--something, for sure), until Father shot out the same kind of "evil eye" that my esteemed choir director has been known, on rare occasion, to send as a warning to an errant member of the group. I relinquished my effort, figured out what key he had landed on, and joined him there. All was again well.
