Question:

What is a good Christmas song to sing for a high school choir concert?

Whenever I do a solo, I usually try to sing something sad and meaningful (like in the past I've done"Only Hope" by Mandy Moore/Jonathan Foreman, "Time After Time" by Eva Cassidy, and "For Good" from the musical 'Wicked'). I don't really want it to be so popular that people in the audience can sing it with me, but it doesn't have to be unheard of. My mother keeps telling me to sing something upbeat, but I'm not sure if I have the type of voice to pull that off. Any suggestions are welcome!! :)
