Chór mieszany z Nakła nad Notecią, pod dyrygenturą Michała Gacka.

We are a group of mostly retired people who enjoy singing together and entertaining others.

The University Choir from Colorado Christian University under the direction of Dr. Frank F. Eychaner performs William Byrd's Sing Joyfully for 6 voices. The a cappella performance was recorded in April 2012 at St. Paul's Lutheran Church in Denver Colorado.
