Singenda Engel, released in English-speaking countries of Singing Angels, purports to relate the history of the Vienna Singing Boys Society. Weaving in and out of the screenplay are selected events from the life of the Society's spiritual mentor, composer Josef "Papa" Haydn. Hans Holt stars as Haydn, while the current members of the Society appear as themselves. As would be the case in the 1962 Disney film Almost Angels (set amongst the performers of the Vienna Boys Choir), the film is at its best when the canary-voiced choristers exhibit non-angelic behavior. Running a full two hours, Singing Angels had trouble securing double-feature bookings outside of Austria.
