For a while opera meant Italian music only; then, with Martha and Stradella, came a sprinkling of the lighter class of German operas. The mixture was healthy and prepared our people for the greater things yet to come. Finally the red-letter day dawned which brought me a degree of happiness that I shall never forget Max Maretzek had an opera troupe in the Federal Street Theatre. He brought out Mozart’s Don Giovanni, with the fine singer Bosio as “Zerlini.” Perhaps my pleasure was heightened by the fact that the director used my score. The copy is one of the earliest published, with the German title-page, Don Juan; or, The Stone Ghost; a Comic Opera in Two Acts. Some few years later; Fidelio, by Beethoven, was performed in the Boston Theatre, and at last we heard the finest music-dramas; and probably no greater enjoyment will ever be derived from any future performance of them than we got from that first one. Of that I am satisfied.
