Question: Rosa Rio providedsilent film soundtrack accompaniment for which English comic actor?

full_context: Document 1: Charlie Chaplin (singer): Richard Patrick Bennett OD, better known by the stage name Charlie Chaplin, is a Jamaican dancehall and ragga deejay and singer. It was common for Jamaican deejays of the era to name themselves after film stars or characters. Bennett, however, had been nicknamed after the comedian since his youth. His career began in 1980 when he began working with U-Roy's Stur-Gav Hi-Fi collective. He became extremely popular throughout Jamaica, memorable for his focus on cultural and social themes instead of the "slack" (rough, violent) lyrics that were popular at the time. His popularity as a live performer prompted Roy Cousins to produce some recording sessions with the young DJ. Chaplin's debut album was the Cousins-produced "Presenting Charlie Chaplin" in 1982, with several albums following for the producer over the next three years.
Document 2: Silent film: A silent film is a film with no synchronized recorded sound, especially with no spoken dialogue. The silent film era lasted from 1895 to 1936. In silent films for entertainment, the dialogue is transmitted through muted gestures, mime and title cards with a written indication of the plot or key dialogue. The idea of combining motion pictures with recorded sound is nearly as old as film itself, but because of the technical challenges involved, synchronized dialogue was made practical only in the late 1920s with the perfection of the Audion amplifier tube and the introduction of the Vitaphone system. During silent films, a pianist, theater organist, or, in large cities, even a small orchestra would often play music to accompany the films. Pianists and organists would either play from sheet music or improvise; an orchestra would play from sheet music.
Document 3: Buster Keaton: Joseph Frank "Buster" Keaton (October 4, 1895 – February 1, 1966) was an American actor, comedian, film director, producer, screenwriter, and stunt performer. He was best known for his silent films, in which his trademark was physical comedy with a consistently stoic, deadpan expression, earning him the nickname "The Great Stone Face." Critic Roger Ebert wrote of Keaton's "extraordinary period from 1920 to 1929, [when] he worked without interruption on a series of films that make him, arguably, the greatest actor–director in the history of the movies". His career declined afterward with a dispiriting loss of his artistic independence when he was hired by Metro-Goldwyn-Mayer and he descended into alcoholism, ruining his family life. He recovered in the 1940s, remarried, and revived his career to a degree as an honored comic performer for the rest of his life, earning an Academy Honorary Award in 1959.

Chaplin became a worldwide icon through his screen persona "the Tramp" and is considered one of the most important figures in the history of the film industry. His career spanned more than 75 years, from childhood in the Victorian era until a year before his death in 1977, and encompassed both adulation and controversy.
Document 7: Cross-dressing in film and television: Cross-dressing in motion pictures began in the early days of the silent films. Charlie Chaplin and Stan Laurel brought the tradition of female impersonation in the English music halls when they came to America with Fred Karno's comedy troupe in 1910. Both Chaplin and Laurel occasionally dressed as women in their films. Even the beefy American actor Wallace Beery appeared in a series of silent films as a Swedish woman. The Three Stooges, especially Curly (Jerry Howard), sometimes appeared in drag in their short films. The tradition has continued for many years, usually played for laughs. Only in recent years have there been dramatic films in which cross-dressing was included, possibly because of strict censorship of American films until the mid-1960s. One early exception was the murderer, a transvestite who wears particularly frilly dresses and petticoats, in Alfred Hitchcock's British thriller "Murder!".
Document 8: Roscoe Karns: Roscoe Karns (September 7, 1891 – February 6, 1970) was an American actor who appeared in nearly 150 films between 1915 and 1964.

Document 11: Charles Bowers: Charles R. Bowers (June 7, 1889 – November 26, 1946) was an American cartoonist and slapstick comedian during the silent film and early "talkie" era. He was forgotten for decades and his name was notably absent from most histories of the Silent Era, although his work was enthusiastically reviewed by André Breton and a number of his contemporaries. As his surviving films have an inventiveness and surrealism which give them a freshness appealing to modern audiences, after his rediscovery his work has sometimes been placed in the "top tier" of silent film accomplishments (along with those of, for example, Charlie Chaplin, Buster Keaton, Harold Lloyd). In comic style, he probably modelled himself after both Harry Langdon and Buster Keaton and was known to the French as ""Bricolo"."
