Don't/I Beg Of You was Presley's eleventh number-one hit in the United States. A double sided hit, it stayed on the charts for 11 weeks.
By this time, Elvis was doing precious little that was wrong, and his range and control were growing geometrically -- thus, amid some powerful rock & roll, including "Mean Woman Blues", "Teddy Bear," the electric guitar-driven "Got a Lot 'o Livin' to Do," Ivory Joe Hunter's "I Need You So," and a hard, brittle-textured outtake of "I Beg of You."
On the Elvis Presley album Loving You, it was actually one of his more coherent and cohesive long-players, assembled from sessions all conducted in the first two months of 1957. ~Source All Music.com
