Catherine Wright was a radio and blues singer best known as the "Mystery Girl, " who would later go on to provide the voice for the animated cartoon character Betty Boop. Catherine started her career on radio where she would sing popular "Boop-Boop-a-Doop" and blues songs, and sometimes toured the vaudeville circuit. In 1929 she signed with Victor Records and Columbia Records, in which she recorded several songs. Catherine Wright's vocals in the Betty Boop cartoon series can be heard in 1933 and 1938. Wright can also been seen performing live in person in the 1934 Fleischer Victory Newsreel, "Boop-Oop-a-Dooping" to the song "Don't Take My Boop-Oop-A-Doop Away" alongside Mae Questel, Margie Hines, Bonnie Poe and Little Ann Little. While singing on radio, Catherine was often mistaken for Helen Kane. In 1929 Catherine appeared in Earl Carroll's revue The Sketch Book. Unlike the other voices of Betty Boop, Catherine's vocals are quite distinctive, as her portrayal of Betty is very nasally.

Out of "Sketch Book" (1929)


Within a week, four girl princlpals and possibly more may be out of Earl Carroll's Sketch Book. When the production had its premiere here Nancy Decker was standing in the wings in street attire waiting for a written release from Carroll. She had obtained a verbal one. Estelle Fratus, the Rendezvous club, gave in her notice, effective next week. Maintained she was poorly spotted. The Mystery Girl, Katherine Wright, extensively exploited on the radio, will be out next week.

"Mystery Girl" Opens (1929)


The radio Mystery Girl, who is under the management of Tom Kennedy, opened for RKO this first half. The program billing asks the questions "What Does She Look Like" and "Who Is She?" We'll take our guess and say that she's short in height, is pretty and has fluffy red hair. As to her name, our guess is that it's Catherine Wright. She has been a favorite with radio fans and opened with Earl Carroll's Sketch Book, leaving it after several performances.

Madison Square Gardens (1929)


Then came saucy little Katherine Wright, red headed and cute as the dickens, to do a bit of impersonating of Helen Kane, the Boop-Boo-Do-Do-De-Boop lady. Miss Kane's the saucy little thing that made such a hit in Sweetie. Remember her? She's the one that sang "He's So Unusual." Katherine did the same song, and gave a very credible impersonation of Miss Kane, too, and followed that up with "Let's Do Something." If our memory hasn't failed us, that also was one of Miss Kane's songs in Sweetie

Betty Boop Production (1933)

Columbia Records

The Mystery Girl

In 1929 Kate Wright recorded as "The Mystery Girl" for Columbia Records anonymously. The artist was later revealed to have been Kathryn Wright/Catherine Wright by discographers. The recordings were Columbia Records crafty attempt to cash in on Helen Kane's popularity as a rival to the Victor Company. The label issued four sides by a anonymous artist called The Mystery Girl. So few sides released suggests that this attempt to exploit Helen Kane's fame was not successful. Wright would provide the vocals for Betty Boop when Betty's main three voice actresses were unavailable.

The Mystery Girl Review

Catherine Wright - I've Got a Feeling I'm Falling

Catherine Wright - I've Got a Feeling I'm Falling

In 1985, The Mystery Girl recordings were reviewed in the paper; "Much less ethical was the brief appearance of "The Mystery Girl" also in 1929 a shamelessly Boopish approach with no holds barred. This was out-and-out copying and in some ways the mystery girl out-Boops the original (Helen Kane). Her dizzy testimonial, "Do I Know What I'm Doing", and the fabulous "I'd Do Anything For You" are shining gems of rinky-dink charm. Halfway through this latter tune she's even agreeing to babies, even though, like turnips she can't stand em. I was also thrilled by her version Fats Waller's "I've Got A Feeling I'm Falling". Her whining little voice wrings out the sweet words just so. The liner notes speculate that this Mystery Gal was none other than Kate Wright, one of the several women who's voices were used for the voice of Betty Boop in the films."
