Marc Martel, who sings Wally’s favorite Christmas song (Downhere’s How Many Kings), makes it look so effortless as he belts out What Child Is This?.

Want to hear Marc sing some more? Wally challenged him to Christmas Karaoke, where they took turns singing lines impersonating famous singers. Marc’s Michael Jackson impression is spot-on.

You can also watch Wally try to accompany Marc on ukulele, and hear Marc tell us what Canadian Christmas is all about.
