[78-L] Interesting Columbia Viva-Tonal

[Don Chichester]

I picked upa copy of CO 2206-D today:  When It's Springtime In the Rockies", Ben Selvin Orch., mx 150430 take 3.
I has a high hum level throughout, UNTIL 3/4 of the way in, someone evidently noticed the hum and corrected it! 
Henceforth the signal is clean and hum-free.  I don't recall hearing any other 78s where the hum is turned off during the 
recording.  Odd.
