After Presley's induction into the army on March 24, 1958, RCA and Presley's manager Colonel Tom Parker were faced with the prospect of keeping his name before the public for two years with no possibility of live performances or movies, and few unissued marketable recordings in the vault. A recording session was arranged for two days in June, which yielded enough items for five more single sides, singles being the commercial focus for rock and roll in the 1950s. Four of those tracks would be issued on 45s in 1958 and 1959 during his absence while doing military service.
