Byla Cesta is a Moravial Christmas Carol, a really beautiful melody in 3/4, and not one that sounds too much like a church hymn.
 
I created an arrangement for String Trio ( 2 violins and cello). Minimum level is lower intermediate, or 'asdvanced beginner' level (Grade 3 players can just manage it, and if you are grade 8, it will sound easy and beautiful :-)
