Single on RCA, July 1963. Writer's name is spelt 'Jimmie' on the label.

The singer:
Val Martinez released at least eight singles, on King* (1954), United Artists (1958), and finally four on RCA (1963) that followed one on RCA subsidiary Groove (1962). 

On his two 1954 King singles Martinez was backed by Bill Doggett's Orchestra.* His RCA single Someone's Gonna Cry (1963) was arranged by Jack Nitzche and produced by Lester Sill who also co-produced You Make Me Happy.

In spite of such distinguished connections, details about Martinez are elusive. Billboard's review of his second single At Last (1954) describes him as using some of the techniques of Johnnie Ray, Billy Eckstine and other stylists. He was still around in 1980, when an entertainment column in The Baltimore Afro-American mentions shows at the Playboy Club at Century City (LA) by Val Martinez, who got his start singing with Bill Doggett... in Detroit.

Martinez's records (mostly Someone's Gonna Cry) are often listed nowadays under the retrospective genres of Northern Soul and its Belgian counterpart Popcorn. He may also be found in a category called Popcorn Soul, at the bouncier end of soul music.

* I'm assuming, plausibly, that the 1954 Val Martinez on King is the same as the Val Martinez on the later singles. A complication is yet another Val Martinez who released four 78s in Spanish on Decca in 1936. Unraveling this is beyond my resources.

The writer:
New York singer, songwriter, producer and label owner Jimmy Curtiss (b. James Stulberger, 1940) had a varied and productive career in music from the late 50s but never became a household name.

Curtiss released two singles in the current teen idol style 1960-61 on United Artists, and one on Warner Brothers (1962), before concentrating on songwriting and working in advertising. He resumed recording with three singles on Laurie 1965-67, of which Psychedelic Situation (1967, co-wr. Ernie Maresca) is the best remembered. He then formed The Hobbits whose records on Decca later became sought after by fans of sunshine pop. From 1969, Curtiss's own label Perception issued records by a number of jazz, r&b and pop artists, the most successful of which was King Harvest's Dancing In The Moonlight (1972). During this period he produced and wrote for a number of lesser-known bands, often in bubblegum or psychedelic pop styles, and released his own album Life using the name J.C. (1969).
