“This Little Girl of Mine” played off “This Little Light of Mine”, much like the previous “I Got a Woman” and the later “Hallelujah I Love Her So” played off other classic gospel hymns. And much like those songs, replaced sacred lyrics with secular blues lyrics with doo-wopcall and response harmonies.
The song was the B-side to Charles’ number-one R&B single, “A Fool for You”, and was a charted hit on its own, peaking at number nine on the chart.
The tune was re-made to top 40 pop status in 1958 by The Everly Brothers. It should not be confused with the 1981Gary U.S. Bonds hit “This Little Girl.” source
