Hello!  The "Yale" appears to be some sort of slow fox -- confer the
following version of the song:

  Homocord-Orchester
  mit Refraingesang: Luigi Bernauer
  Homocord 1929

 [ In the context of a record label, "mit Refraingesang: Luigi Bernauer"
 [ translates as "with chorus sung by Luigi Bernauer".  I measure 91
 [ beats per minute -- a nice, medium-slow foxtrot tempo -- across
 [ the 32-bar refrain that Luigi sings.  -- Editor (Robbie)
