Question: Who played the composer of "The Liberty Bell" in Stars and Stripes Forever? 
Context: The Liberty Bell was the first variation of the modern mechanical slot machine we see today, originally being referred to as a ""fruit machine"" or ""one-armed bandit"".  Created in 1895 by Charles Fey (1862–1944), a car mechanic from San Francisco, the Liberty Bell's popularity set the standard for the modern slot machine; its three-reel model is still used today despite great advances in slot technology over the past several decades.  The original Liberty Bell slot machine is currently on display at the Liberty Belle saloon in Reno, Nevada as a historic artifact. Liberty Bell Mountain is located in the North Cascades, approximately one mile south of Washington Pass on the North Cascades Highway.  Liberty Bell is the most northern Spire of the Liberty Bell Group, a group of spires which also includes Concord Tower, Lexington Tower, North Early Winters Spire, and South Early Winters Spire. The Justice Bell ("The Women's Liberty Bell") is a replica of the Liberty Bell made in 1915.  It was created to promote the cause for women's suffrage in the United States from 1915-1920.  The bell is on permanent display at the Washington Memorial Chapel in Valley Forge National Park in Pennsylvania. Liberty Bell refers to one of two replicas in Portland, Oregon, United States, of the original Liberty Bell in Philadelphia.  The first replica was purchased in 1962, and installed in the rotunda of City Hall in 1964.  On November 21, 1970, it was destroyed in a bomb blast that also damaged the building's east portico.  The second replica was installed outside of City Hall soon after the blast (c. 1972) with funds from private donations.  It was constructed at the McShane Bell Foundry in Baltimore and dedicated on November 6, 1975.  The bell is listed as a state veterans memorial by the Oregon Department of Veterans' Affairs. John Philip Sousa ( ; ; November 6, 1854 – March 6, 1932) was an American composer and conductor of the late Romantic era, known primarily for American military and patriotic marches.  Because of his mastery of march composition, he is known as "The March King", or the "American March King" due to his British counterpart Kenneth J. Alford also being known by the former nickname.  Among his best-known marches are "The Stars and Stripes Forever" (National March of the United States of America), "Semper Fidelis" (Official March of the United States Marine Corps), "The Liberty Bell" (used as the theme for Monty Python's Flying Circus), "The Thunderer" and "The Washington Post". The Taco Liberty Bell was an April Fool's Day joke played by fast food restaurant chain Taco Bell.  On April 1, 1996, Taco Bell took out a full-page advertisement in seven leading U.S. newspapers announcing that the company had purchased the Liberty Bell to "reduce the country's debt" and renamed it the "Taco Liberty Bell".  Thousands of people had called Taco Bell headquarters and the National Park Service before it was revealed at noon on April 1 that the story was a hoax. Stars and Stripes Forever is a 1952 American biographical film about late-19th-/early-20th-century composer John Philip Sousa, played by Clifton Webb.  Sousa is best known for his military marches, of which "The Stars and Stripes Forever" is arguably the best known. The Liberty Bell Pavilion was a building within Independence National Historical Park (INHP) in Philadelphia, Pennsylvania, that housed the Liberty Bell from January 1, 1976 to October 9, 2003.  Designed by the architectural firm of Mitchell/Giurgola Associates to be the Bell's permanent home, it stood for only 30 years.  The Bell is currently housed in a much larger building, the Liberty Bell Center, completed in 2003.  The Pavilion was demolished in 2006. The Liberty Bell is an iconic symbol of American independence, located in Philadelphia, Pennsylvania.  Formerly placed in the steeple of the Pennsylvania State House (now renamed Independence Hall), the bell today is located in the Liberty Bell Center in Independence National Historical Park.  The bell was commissioned in 1752 by the Pennsylvania Provincial Assembly from the London firm of Lester and Pack (known subsequently as the Whitechapel Bell Foundry), and was cast with the lettering "Proclaim LIBERTY Throughout all the Land unto all the Inhabitants Thereof," a Biblical reference from the Book of Leviticus (25:10).  The bell first cracked when rung after its arrival in Philadelphia, and was twice recast by local workmen John Pass and John Stow, whose last names appear on the bell.  In its early years the bell was used to summon lawmakers to legislative sessions and to alert citizens about public meetings and proclamations. The Liberty Bell Museum (also the Liberty Bell Shrine Museum) is a non-profit organization and museum located in Zion's United Church of Christ (formerly Zion's Reformed Church) in Allentown, Pennsylvania, in the United States.  The museum, based in the church in which the Liberty Bell was hidden during the American Revolutionary War, contains exhibits relating to the Liberty Bell and subjects including liberty, freedom, patriotism and local history.  The shrine was founded in 1962 by Dr. Morgan D. Person.  Between 1962 and 1971, Interstate 178 was planned to go through the location of the museum, but opposition cancelled the expressway.
