This was one of the first LP releases to introduce the concept of audio restoration to the general public. although that term was not yet in general use. As mentioned above, a free promotional paper record was sent to Reader's Digest subscribers introducing the set, with Vaughn Monroe presenting "Before" and "After" versions of one of the songs to demonstrate what had been done to enhance the sound. As described in the booklet accompanying the records, each song was transferred from a new matrix, then electronically treated to remove surface noise as well as "ticks" and "pops." Although there is still some residual surface noise on a few of the tracks, the restoration overall was remarkably successful.
