For today's Thanksgiving holiday we have a recording of the  Akathist of Thanksgiving.  An akathist is a long Orthodox hymn.  It consists of thirteen parts, each made up of a kontakion followed by an ikos.  These are varieties of Orthodox hymnody.  The text of the Akathist of Thanksgiving was written by Protopresbyter Gregory Petrov, a Russian Orthodox priest who died in 1940 after being swept up into one of Stalin's gulags.  The text can be found here.
