What a load of rubbish.
I really enjoyed the group sing-a-longs on BB2 and last year they composed a song for Tim and were singing about the house. Why not is what I say
What are they going to do if someone has a musical moment (as we all do) and actually dares to sing a song.
Dont think they will be able to enforce this rule, or at least I hope not. It also makes me realise that its not just me who cant sing, but loves having a go.
BRING ON THE SINGING !!!!
