Hal began playing professionally in late high school at various movie houses and dance halls. These included most of the movie houses of the time including the Midwest Theatre, the Trianon, Fox Sheridan, Granada, the Terminal, and others. He was often promoted as a "Boy Wonder" and as "Chicago's Youngest Organist." At 25 years old, Hal was named the official organist of the
Century of Progress, the 1933 Chicago World's Fair. During that time (and after), he was the organist at the
White City Amusement Park on Chicago's south side. Hal Pearl is probably best known for being the organist at the
Aragon Ballroom for over 20 years. The Aragon hosted nearly all of the top names of the big band era. Hal was the resident organist during that era, playing with and during the intermissions of the sets of the visiting artists. Shows were radio broadcast nationally and even heard in Europe. Hal Pearl was the organist for Chicago's tumultuous
1968 Democratic National Convention. He recalled being bused in with other members of the orchestra with heavy police protection. Hal was non-political and also played for Republican Vice President Spiro Agnew and President Richard Nixon. Other venues included downtown theaters such as The Oriental (now
Nederlander) Theater,
Chicago Theatre, and others such as The Willowbrook (O Henry) Ballroom. He played at Orchestra Hall, home of the Chicago Symphony Orchestra. Hal also played numerous conventions and shows such as the Chicago Flower Show at
McCormick Place, events at the
Chicago Coliseum, the
Chicago International Amphitheatre, and others. He was the first organist to introduce dancing to organ music. Hal was the organist on the PBS television series
The Toy That Grew Up which broadcast movies from the silent era. Producer Robert Seipp researched each film he presented with a
pipe organ score provided by Hal; the on-screen host of the show was Don Ferris. The show was syndicated and broadcast on over 30 public television stations from 1962 to 1972. Hal Pearl gave a sold-out organ concert at the reopening of the
Chicago Theatre on Thursday evening, September 18, 1986. Hal's organ show re-introduced the Chicago Theatre's massive pipe organ to the public and followed a concert by Frank Sinatra on September 10. Hal was the headliner at the organ concert, the opening organist being a younger musician. Gregory Pearl, a family member, overheard comments in the lobby at the concert where people said, "The kid can play the organ, but the old man (Hal) can make it sing." Hal was the frequent headliner at organ shows at the
Patio Theater in Chicago from the 1960s until shortly before his death. == Educational activities ==
