Reading about the Spanish Civil War here, I'm reminded of a book I've just 
finished reading, called ZigZag, about WW II british spy/espionage, and got 
to wondering about the German magnetic tape machines that were found in 
Germany during/after the war. What were the first U.S. record companies to 
use this medium for recording? When? Anyone know the progression of events 
in this field? Equipment? Wasn't this the beginning of having the capability 
to overdub easily?
