Two of the anthems sung by the Union Chapel choir last Sunday were new arrangements of Harry T. Burleigh’s “Were You There When They Crucified Him” and “Deep River.” Mr. Burleigh, one of the country’s eminent composers, was present in the congregation. Mr. Burleigh is, as well, a noted baritone whose voice is heard over the radio from the vespers of St. George’s Episcopal Church, New York, where he is a soloist. He is a regular summer visitor to Oak Bluffs.
