Pain in My Heart [SEP] Recording and release
"Pain in My Heart" includes songs from Redding's 1962–1963 sessions. Stewart signed Redding for Stax and released Redding's debut single, "These Arms of Mine", with "Hey Hey Baby" on the B-side. "These Arms of Mine" was released by Volt, a subsidiary of Stax, in October 1962, and charted in March the following year. It was one of his most successful songs, selling more than 800,000 copies. In the 1963 session, "That's What My Heart Needs" and "Mary's Little Lamb" were recorded and cut in June 1963; the latter became one of the worst-selling singles by Redding. Rob Bowman, in his book "Soulsville, U.S.A.: The Story of Stax Records", wrote that in these two songs "Otis sings with a harsh, impassioned gospel voice reminiscent of Archie Brownlee of the Five Blind Boys of Mississippi" and further reckoned the ending of the first would have made Redding "a superb gospel singer had he chosen to record in that idiom." "That's What My Heart Needs" became Redding's second single on Stax.
