so I was just listening to Sing and thought wouldn't it be great if Karen and Richard sang the "La la la" bits instead of the children's choir. They could have overdubbed it like the "Waaa's" on Close To You or the "sha la la" 's on Yesterday Once More. It would have been great to hear or at least interesting. I think if they did that with sing it could have been a bigger hit and become a bigger fan favourite. Any thoughts?
