"Locking Up My Heart" is a 1963 single released by Motown girl group The Marvelettes on the Tamla record label.
The track was recorded 8 January 1963 in Studio A Hitsville USA and released 15 February 1963; the B-side: "Forever", was a cut from the 1962 Playboy album, written and produced by Holland–Dozier–Gorman (H-D-H's predecessor), and also featured Young as lead vocalist.
On the single's initial A-Side, Horton, as the main lead and narrator, tells the audience that she's giving up love, as she's "tired of being abused" and "mis-used".
"Locking Up My Heart" broke out in Baltimore and San Francisco to enter the Billboard Hot 100 dated 23 March 1963 at #83; Motown considered the track to be significant enough to re-press it with adjusted instrumentation that April.
"[3] Cash Box described Marvin Gaye's 1964 cover of "Forever" as "a slow-shufflin' tradition-styled blues lament rendered with loads of authority and feeling.
