Idu nyňi ko krestu
This hymn is frequently sung before or after services on the weekdays of the Great Fast, but would be more appropriate during Great and Holy Week, particularly on Great and Holy Friday. The text is that of Monsignor William Levkulic (see below), who also published an English setting, Now do I go to the Cross.
