Also for your listening pleasure this Fourth of July, Paul Simon and Art Garfunkel join forces to cover Simon’s classic, “American Tune.” Episcopalians of course recognize the melody as hymn 168 in the 1982 Hymnal, “O sacred head, sore wounded,” written originally as part of Hans Leo Hassler’s “Passion Chorale” and adapted and harmonized later by Johann Sebastian Bach. God bless America.
