After looking at some of the other reviews I have to wonder if they even bothered to read the booklet that comes with this set. The first page contains an entire paragraph on the evolution of this compilation, how it come to be labeled "Volume 2" and the addition/deletion process related to the selections.
The remainder of the 5-page booklet (counting the inside cover) contains photographs showing the receipt and sorting of Elvis' discarded clothing, portions of which accompanied each issue of the original vinyl four-record set in 1971, and a complete listing of Elvis' Recording Industry Association of America certified multi-platinum, platinum, and gold award records. Two full pages also show the evolution of the original box cover for the vinyl set and a reproduction of the hand-written page showing a list of the additions and deletions.
Historical references aside, the music contained herein offer up many of the flipsides of his hit singles, most of which charted on their own. In fact, from 1956 to the release of (You're The) Devil in Disguise in 1963, both sides of his single releases always made the pop charts, a record unmatched in the history of music (not even The Beatles could match that). The B-side to that 1963 single which ended the string of two-sided hits was Please Don't Drag That String Around (track 12 on Disc 2).
In selecting One Night, His Latest Flame, and Ask me for "the other sides" collection, I am assuming that each started out as the intended B-side. If that is the case, it's interesting to note that each scored higher than the original A-sides: One Night reached # 4 in late 1958 while the reverse, I Got Stung, made it to # 8; His Latest Flame - also shown as [Marie's The Name] His Latest Flame - topped out at # 4 in September 1961 while the flip, Little Sister, settled for a # 5; and Ask Me peaked at # 12 in late 1964 while Ain't That Loving You Baby (actually recorded in 1958) reached # 16.
A set worth having in your collection.
