Ah so that is how it is done. Put on some backing music , well no, worse still, some music tracks from the internet (that Youtube one is very familiar at our house) and then get the kids to sing along. But not be heard. Have terrible costumes. Come into the room to a very contemporary pop song. Why that song? Why? Get the kids to talk into mikes turned up really loud so that they cannot be heard because of distortion. Completely baffling. Only my extensive experience enabled me to work out that this was the nativity play. As for some of the hand gestures the children had been taught and were being encouraged to use while singing...... words fail me. I expect it ticked some boxes on the EYFSP or whatever they call it now. For ICT. Bring back Real Music.
