Barrington Hooper

When shooting a Pathétone short film with him (singing a patriotic song), Pathé marketed Barrington Hooper as "the celebrated tenor of Royal Opera House, Covent Garden, BBC etc." Since Covent Garden online archives only feature the post-WWII period, it's impossible to know what Hooper sang there, except for a few Meistersinger performances in June 1925, with Friedrich Schorr, Fritz Soot, Lotte Lehmann, Richard Mayr, and under Bruno Walter's baton, where Hooper was Kunz Vogelgesang.

In less prominent contexts, though, he sang main parts: in the 1922/23 season at the Old Vic in London, he sang Turiddu and in Zauberflöte (I suppose Erster Geharnischter rather than Tamino, but am not sure); in 1923/24, he was Don Ottavio at the New Oxford Theatre in London; and in 1925, he toured with the British National Opera Company, appearing at least in two roles, as Don José and Turiddu. In November 1933, I find him participating in a mixed operatic concert at Royal Albert Hall.

He was also a radio pioneer and must have made a considerable number of records: under his own name, on HMV (where he was also part of the anonymous Light Opera Company), on Vocalion, Columbia, Edison and Pathé; as Petty King on Regal; as Everton Harvey on Ariel.
