Ds1 is nearly 8 and came out of school this week clutching a consent form for the school choir, which meets twice a week after school. They take dc from Year 3 so this is a new opportunity for him.
He's really excited, really, really wants to sign up.
BUT he is tone deaf. Completely. He is good at plenty of other things and has no lack of activities he does already...but there's no nice way to say it, I have never heard any child with such a truly awful singing voice. He even loses the tune singing simple nursery rhymes, and always has since a toddler.
It's kind of never been brought up. I'm not in the habit of telling the dc they're fabulous at everything (you know the type). But I mean, when your 3/4/5 year old sings the songs they're learning at school for you, you automatically go 'Oh that was lovely, well done for remembering it all' or similar. Which is just what I've done with ds, whilst gritting my teeth. So he doesn't know or realise he can't sing as far as I can tell. He's mentioned asking the teacher if he can sing a song he's learnt recently to see if the other kids know it (old school, unusual song). He seems quite keen to do a solo 
I'm genuinely worried he'll be made fun of and laughed at, and I don't want him to go and be brought crashing down by the other kids 
Do I:
A. Make up an excuse as to why he can't go (such as I have to do X on those nights, maybe next year, and hope he loses interest)
B. Tell him he can't sing and can't go (gently)
C. Let him go and hope for the best.
