Jack Berger & His Hotel Astor Orchestra - Sweetheart Darlin'

I couldn't retrieve any information on Jack Berger's Hotel Astor Orchestra. They recorded six sides for Bluebird in 1933, six sides for ARC in 1931 and two sides for Crown in 1932. The vocalist with the band was variable, but several sides, including this one featured Ted Holt, an excellent vocalist equally unknown to me. This lovely record was made in 1933.
