The maintenance of the songbooks of the San Antonio Mannergesang-Verein seems to have been a divided responsibility, for, in noting the preparations for an October 25, 1851 concert, the secretary remarked that the following men had readied the books: Albert Moye and Christian Schleyer, the first tenors; C. N. Riotte, the second tenors; J. T. W. Simeon, the first basses; and Herman Wille, the second basses.
