I have no idea who the singers or players were on this recording. The recording dates and names of the groups are listed in DAHR, but no specifics. But, a nice electrically recorded singing group.
I think it is interesting and strange that a record like this would have been made as late as 1929. It is very old fashioned when compared to the terrific jazz and pop tunes being recorded at that time by Victor, Columbia, Brunswick, and even Edison. And, I know there were many better, or at least more potentially popular, records ultimately not released by Edison as they went out of business. This is pretty and well done. But, who would have actually purchased this record in 1929?
A little noise at the beginning then pretty clean.
