In almost 26 days, you will be performing your last concert in primary school. Therefore, you need to learn the lyrics of the songs to be able to sing loud and clear. You need to show commitment, enjoyment, a positive attitude and an excellent disposition when you are rehearsing so that you all excel in your performances.
Mahatma Ghandi once said:
"You might be the change you wish to see in the world" I would adapt it to this situation in particular and say:
"You might be the change you wish to see in the concert"
What do you think??
