In fact this lovely song is by Nat Shilkret and his Orchestra, and on this record the credits apply more in general to all performers, although the actual Troubadors (or Troubadours) were a vocal trio occasional recording in the late 20's, and consisting of Leo O'Rourke, Phil Dewey and Frank Luther. This pretty waltz was a theme song from the 1929 film "The Godless Girl", and was recorded in 1928.
