Listen to the mocking bird

Yesterday afternoon was unseasonably warm for late winter. I celebrated by playing guitar on my front porch. I was working out a walking bass arrangement of the 1935 Rodgers and Hart standard Blue Moon, the version that goes:

'Blue moon, you saw me standin' alone
Without a dream in my heart
Without a love of my own
Blue moon, you knew just what I was there for
You heard me sayin' a prayer for
Someone I really could care for...'

A blue-tinged sparrow, attracted (or possibly annoyed) by my playing, landed on a branch of the crab apple tree sheltering the porch and proceeded to tweet. Unfortunately, the bird was tweeting in the key of A flat, whereas I was playing in the key of C. The discordance was distracting to me. The bird didn't like it either and flew off to a tree beyond the swimming pool.

I resumed my Blue Mooning. But soon the bird returned and made a racket in A flat once again. I held my ground and insisted on the key of C. You can't let a bird push you around. Otherwise, the neighborhood squirrels and rabbits start getting ideas.
