[GreenKeys] The Metric System (was Independence Day

Fri Jul 7 17:39:13 EDT 2017

     I now find that the recording by Paul Whiteman was probably played 
at a faster tempo than the original live performances in order to get it 
to fit on the record. Common when the longest time available was around 
6 minutes per side for a 12" 78. Nonetheless it does not explain the 
similar tempo found on the piano roll other parts of which are rather slow.
