Good A Capella Arrangement of Let It Snow

I was listening to the radio recently and heard an a capella arrangement of Let It Snow by Ricochet.  They have a music video here.  Ricochet is a country music group, but you shouldn't write them off because of that.  The arrangement is a capella and is quite good (and there really isn't much country in it).  I'm surprised it hasn't attracted my attention before, since it's a relatively old song (from 1996).
