Thank you very much! Always appreciate positive feedback.
This is one of those old, old, old Christmas carols that is usually sung about 4x slower than my version by a full choir, which makes it drag out to over 12 minutes in some cases, haha. Regardless I liked the melody and whenever I cover an existing piece I try to change it as dramatically as possible, to give it my own flavour. In this case that meant bringing the tempo up to a lively pace and playing around with bouncier rhythms. Something about crazy pizz strings and enthusiastic cello sounds seemed to lend itself to the tune.
Glad you liked it, anyway. Cheers!
