Composer of Sweeney Todd: The Demon Barber of Fleet Street (Broadway, 1979), needed for the 1979 original Broadway cast recording. findopera already carries other Broadway scores and their cast albums (Kiss Me Kate 1141 / Porter, Show Boat 1140 / Kern, West Side Story 674 / Bernstein, and Paul Gemignani as conductor of Crazy for You 4094 and Man of La Mancha 4026), so this fills a gap rather than opening a new category.
