[78-L] Limited edition Miller

[William A. Brent]

for the longest time, I've had 2 multi disc Glenn Miller albums - 
they seem to date from 1954.
the first set is on EPs (45s) the second is on LPs. most of the 
tracks seem to come from
radio broadcasts. Does any one know the history of these? was the mid 
50's a special time for
releasing radio broadcasts (Decca was doing this with Jolson) - then 
again, RCA did this in
the 60's with Lanza.
But did RCA not have enough studio material in 1954 to release sets 
of this size?
did these sell well?
