With a nod to pogo333, clearer A side label image added. B side label image added. A side is also a label variant. The label images listed as "More images" are from Columbia cat.# A1885. The mx number for the title "Serenade" on Columbia cat. # A1863 is 46167. The mx number for "Serenade" on cat. # A1885 is 46168. Both recorded Oct. 29, 1915 and both are take 1 (DAHR). I do not know if these are the same recordings with different mx #'s or different recordings. DAHR lists the release year as 1916.
