Pearl and Vi had individually sung in Cumberland, Maryland, theaters and won prizes for their song competition accomplishments.

Pearl's early sheet music learned inspiration's came from the compositions of Chopin, and Stephen Foster.The Hamilton Sisters found their harmony singing blend in Cumberland.

She was on the Brooklyn vaudeville circuit and beyond; as a young child star, "Baby Helen", her stepping-stone success through songs and vocal imitations had impressed the masses.

Pearl started out as a soft shoe (ballet style) and high-kick dancer, and received positive dance reviews.

Pearl watched a live performance of the Original Dixieland Jass Band in the Coney Island, New York scene, after her arrival to Broadway stages.

The Hamilton Sisters and Fordyce earliest known performance together (as a trio team) was at B.F. Keiths Theater in Syracuse, New York, on May 13, 1923.

[12] In 1926, the trio toured with another popular all-girl act, Jerry and her Baby Grands,[13] appearing together at the Palace Theater in New York.

After they departed from the "Stars of the Future"[9] entertainment showcase in the spring of 1927, their management, fronted by Ed Wolfe, had them tour Europe.

They departed by airplane at a Long Island airport with the American portion of New York's Savoy Orpheans musical unit during the week of May 23, 1927.

They also spent time in the recording studio with Bert Ambrose, a British bandleader, musical director Caroll Gibbons, and violinist/director Reg Batton.

On October 27, 1927, Harry Plunket Greene, Irish baritone tenor, wrote of the trio after an England performance: "The Hamilton Sisters & Fordyce are just A1 as they are.

When the popularity of the vaudeville on stage showcase Playtime[20] had become a real success, it attracted the attention of Broadway play Rain or Shine in early 1928.

She chose to tour the US extensively, and sign with such sponsors as Ford, Chase and Sanborn, Best Foods, Tydol, Babbo, and others to pursue the radio career for her trio.

Some radio transcribed tunes which they sang to identify the 1930s era in rhythm and the blues are "Old Clothes", "Good Times Coming", and "Still No Luck With You" (with Pearl's piano, and Steve Brown (bass player)).

Pearl's piano style was crafted exclusively on their Musical Grocery Store radio tenure, alongside the Harry Salter Orchestra.

They attributed voice-work for the popular Max Fleischer Cartoons synched with their early radio-work, and by 1933 they had a regular time-slot with NBC Radio.

In 1932, the Three X Sisters were part of the CBS Tydol Jubilee Show and toured for a while with one of the hottest dance bands in the country, Paul Specht and His Orchestra,[25] which was also popular with the college audience.

The Audition, 1932, featured a few acts, including the trio backed by the jazz guitarist Eddie Lang (heard but not seen in film).

During the summer/fall 1932, the " X Sisters" were signed with Tidewater and the Freddie Rich Orchestra for three times a week with CBS, and continued with Paul Specht on other nightly radio programs throughout that year.

[27] In 1934, they had many guest spot appearances alongside Mary Small on her Little Miss Bab-O Program (Babbitt Company—a detergent soap company).

[28] On Sunday April 8, 1934 the trio shared the guest spot on the Bab-O show with Mario Cozzi, a New York baritone singer on WEAF.

Many Three X Sisters songs were featured during 1934, as well as in April and July during guest appearances on Little Miss Bab-O's Surprise Party with Mary Small and (William) Bill Wirges and His Orchestra.

In August 1934, the X's (were also Bab-O's guests) - then Mary Small, Jimmy Wallington, and other NBC personalities were performing at the Steel Pier in Atlantic City, NJ.

In mid-February 1935, they were touring Chicago and broadcast over WJZ on Monday and Wednesday, until their arrival back in New York after March 2, as 1935 in music also proved to be a popular time for them.

[34] Rumors about their radio departure reached the entertainment pages early in the year, however, not before the songbirds put together some of the best blues styled harmonies.

Pearl had musical connection's of this era, with some band members of the Dorsey Brothers, Harry Salter, Bill Wirges, and Ernie Watson Orchestra's.

In 1939, the Three X Sisters teamed up with such musical act's, in March with Rita Rio in a "new Swing Review", Gerald Griffin with a collaborative song "Jive Rumba", and by the end of the year, again with Mary Small.

A Three X Sisters reunion took place January 26, 1941 on NBC radio with Graham McNamee on his Behind the Mike program (this can be listened to online), where it reintroduced their harmony singing.

[35]' In March 1941, the song was featured on the Morely's "On Page Two"[36] script programs on local Brooklyn, New York WBBC and WEVD stations.

[37] Jessie became Cookie Carr, the character for the jingle; also sang duets (live on stage) with Artie Dunn, of the Three Suns.
