I just got a fill page from the August 28, 1954 issue of Billboard Magazine. The C&W Chart for Memphis has one of the first appearances by Elvis, with Blue Moon of Kentucky at #3. Elvis’ last name is misspelled “Prisley”
There is also another Elvis related news item on the same page. It is mentioned in a news article that Colonel Tom Parker is currently completing negotiations to represent motion picture star John Carroll. I do not believe that an agreement was ever reached. Carroll had a long career stretching from 1929-1974.
