Their talents in demand, Kerr's group continued to sing backup for other country artists in Nashville, including Eddy Arnold, Burl Ives, and Ernest Tubb.

[1] In 1956, Anita Kerr's singers won a contest on the Arthur Godfrey's Talent Scouts national television program.

A few years later, Kerr and her singers performed five times a week with Jim Reeves on his national radio program at WSM.

Subsequent RCA Victor LPs extended the quartet's repertoire as they explored the soul songs of Ray Charles and the compositions of Henry Mancini.

Using Kerr's arrangements, they can be heard on songs by Hank Snow, Brenda Lee, Perry Como, Pat Boone, Rosemary Clooney, Bobby Vinton, Roy Orbison, Willie Nelson, Floyd Cramer, Al Hirt, Ann-Margret, and many other artists.

In 1964, together with Chet Atkins, Bobby Bare and Jim Reeves, the Anita Kerr Singers toured Europe.

In the 1960s, Kerr composed and recorded numerous jingles for use by American radio stations, including: Gene Autry's KMPC AM-710 in Los Angeles, California; WMCA AM-570 in New York City; WLS AM-890 in Chicago and at WGH AM-1310 in Newport News, Virginia.

Disguising the group as the Mexicali Singers, Kerr also recorded a trio of mariachi-flavored albums with musical arrangements reminiscent of the Herb Alpert & The Tijuana Brass sound.

In 1967, Kerr, collaborating with poet Rod McKuen, composed, arranged, and conducted music for an instrumental/spoken-word album called The Sea.

The Anita Kerr Singers Reflect on the Hits of Burt Bacharach & Hal David was the group's first and Edison-Award-winning album for Dot.

That same year, Kerr wrote original music and lyrics for the Ampex album A Christmas Story, and she felt privileged to conduct the Royal Philharmonic Orchestra during the recording sessions.

[11] During these years, Kerr also wrote choral and instrumental arrangements for Hal Leonard Corporation, the world's largest music print publisher.

In 1975, Kerr received a special ASCAP Award saluting "[a] lady of class and a first-class musician for her significant contributions to the birth and development of the Nashville sound.
