Correcting the conductor

The newly formed resident choir of our parish--for which I'm singing alto!--held its third rehearsal earlier tonight. Our conductor was pretty sharp as usual, quickly correcting us whenever we sang sharp or flat and when we were tended to drag or rush with our singing. That is, except for a few minutes when we were all singing together and because we didn't sound right, he kept interrupting to check on the singing of the altos. This happened two or three times until--as much as I hated to embarrass him by correcting his singing--I mustered the courage to approach him and say, "Ikaw yata ang late," referring to the tenor part which he was singing incorrectly because he kept coming in a measure late.
