I vote leave now. Start the holidays early...
We're actually doing this independent study option because I was nervous about letting her totally unschool. We didn't know if we would want to go to the local school after the holidays, but at this point, I'm keeping Butter at home at least the rest of the year.
If you feel guilty, you could always throw a book you think would be "good for him" at him and use that as a vocab, grammer, literature and character analysis assignment. Or make him watch some History channel them report back.
Also, google "gifted home schoolers forum" and you can find a local homeschool group...that might be a starting place for a replacement choir
