Background: George Michael Cohan (July 3, 1878 - November 5, 1942), known professionally as George M. Cohan, was an American entertainer, playwright, composer, lyricist, actor, singer, dancer and producer. Cohan began his career as a child, performing with his parents and sister in a vaudeville act known as "The Four Cohans." Beginning with Little Johnny Jones in 1904, he wrote, composed, produced, and appeared in more than three dozen Broadway musicals. Cohan published more than 300 songs during his lifetime, including the standards "Over There", "Give My Regards to Broadway", "The Yankee Doodle Boy" and "You're a Grand Old Flag".
Context: Cohan was born in 1878 in Providence, Rhode Island, to Irish Catholic parents. A baptismal certificate from St. Joseph's Roman Catholic Church (which gave the wrong first name for his mother) indicated that he was born on July 3, but Cohan and his family always insisted that George had been "born on the Fourth of July!" George's parents were traveling vaudeville performers, and he joined them on stage while still an infant, first as a prop, learning to dance and sing soon after he could walk and talk.  Cohan started as a child performer at age 8, first on the violin and then as a dancer. He was the fourth member of the family vaudeville act called The Four Cohans, which included his father Jeremiah "Jere" (Keohane) Cohan (1848-1917), mother Helen "Nellie" Costigan Cohan (1854-1928) and sister Josephine "Josie" Cohan Niblo (1876-1916). In 1890, he toured as the star of a show called Peck's Bad Boy and then joined the family act; The Four Cohans mostly toured together from 1890 to 1901. He and his sister made their Broadway debut in 1893 in a sketch called The Lively Bootblack. Temperamental in his early years, Cohan later learned to control his frustrations. During these years, Cohan originated his famous curtain speech: "My mother thanks you, my father thanks you, my sister thanks you, and I thank you."  As a child, Cohan and his family toured most of the year and spent summer vacations from the vaudeville circuit at his grandmother's home in North Brookfield, Massachusetts, where Cohan befriended baseball player Connie Mack. The family generally gave a performance at the town hall there each summer, and Cohan had a chance to gain some more normal childhood experiences, like riding his bike and playing sandlot baseball. Cohan's memories of those happy summers inspired his 1907 musical 50 Miles from Boston, which is set in North Brookfield and contains one of his most famous songs, "Harrigan". As Cohan matured through his teens, he used the quiet summers there to write. When he returned to the town in the cast of Ah, Wilderness! in 1934, he told a reporter, "I've knocked around everywhere, but there's no place like North Brookfield."
