Cancelled by an ice storm on Jan.4, “Christmas at the Organ” has been renamed and rescheduled for 3 p.m. this Sunday at Covenant Central Presbyterian Church, 807 West Fourth St. The performing organists will show their creativity by adapting the concert to fit the January Epiphany Season. “Sunday at the Organ” will feature tunes you will know in interesting organ colors. There will also be the Williamsport premier of two organ works discovered in the Royal Music Library in Brussels and heard for the first time in 320 years just last November. Dr. Marcos Krieger will be presenting these two very special works. Also playing in the concert are Leatha Kieser, Carol Waltz, Kenneth Elkin, Donna Zierdt Elkin and Susquehanna University student Gabriel Eherts.
