More than three years later, I've found an answer to the question of the origin, ownership and pressing of Crown records in Lachine. On the Canadian Antique Phonograph Society site is an overview of the beginnings of the Canadian recording industry.
Herbert Berliner (son of Emile Berliner, who patented the lateral cutting method on flat discs in 1887) established the Compo company in 1919, its initial business having been contract pressings for other labels. In 1921, Berliner and other executives resigned from Berliner Gramophone Company and set out to expand Compo operations. The same year, Compo contracted with the Plaza Music Co. of New York, to issue their multiple lines of dime-store records in Canada, which they did until 1936. Crown was one of these labels, and for reasons undocumented, they typeset the labels to read "Crown Record Co. Lachine Montreal Canada."
It will be interesting to see, if anyone ever posts any other Compo-pressed Plaza Music labels, whether the perimeter text is changed to, e.g. Banner or Regal Record Co. Lachine etc.
Ah, Frank Luther - one of the most prolific vocalists ever! Not just "country", he was "vocal refrain" on countless danceband records too where the names of the bands and song titles were constantly changed on different labels. I no longer have access to Brian Rust's extensive jazz and danceband discographies but remember many of his entries cross-referencing a bewildering array of releases under different names. If we thought 45cat sometimes got messy, we ain't seen nothing yet. The 78 era was a free-for-all with no holds barred and little legal protection of copyright.
I believe you're right, mickey. I Googled "Buddy Bartlett A Gay Caballero" and there is a link to a book preview of "Country Music Records: A Discography 1921-1942." According to the book, the artist here is Frank Luther. It's unclear whether these two sides were released together anywhere else, but they were released separately on different records under the names of Frank Evans, Weary Willie, Frank Lewis, Dick Porter, Frank Marvin, Lazy Larry, and Allan Royal on a dizzying array of labels: Jewel, Oriole, Challenge, Homestead, Conqueror, Sterling, Microphone, Paramount, Broadway, Angelus, Gracelon, Starr, Worth, Perfect, Cameo, Lincoln and Melotone. What a tangled web!
I could be wrong, but if this was sourced from the U.S. Domino label it's possible that "Buddy Bartlett" is a pseudonym for somebody else entirely. Domino, along with Banner, Regal, Jewel, Oriole and Romeo were all U.S. budget labels within the Plaza Music Co. empire. The same records were generally released on all of these labels, sometimes with different artist names. These records were then sourced to overseas labels and the artists names were sometimes changed again. But then maybe Buddy Bartlett was a Canadian artist and I'm barking up the wrong tree.
I can find nothing about Buddy Bartlett, or whether Crown was a Compo label or the precursor to the Compo name, as the perimeter text is identical to other Compo 78s - Lachine, Montreal, Canada. The record is brown, and the recording is acoustic.
