When Soprano line is split during the refrains, I recommend splitting all sopranos and altos into 3 parts, as opposed to just splitting sopranos. The same thing applies to tenor and bass parts from measures 59-66. There is a soprano alto trio in the middle of the songs that could be cut or taken down an octave, but it would take away from the piece as a whole.
