These recording are mostly Ellis Street Singers, but there is also a Woman’s Chorus selection as well as an instrumental selection. None of the recordings were done professionally, but are recordings that Dr. Wortman or a member of the group recorded at the performance. Some of the audio files were originally reel to reel recordings, but have been digitized to help preserve the quality of sound. There is also a collection of cassette tapes, a few VHS tapes of the performances and three 8mm film.
