"Cheer Up, Mother" is a World War I era song released in 1918. Mary Earl composed the music and wrote the lyrics. Shapiro, Bernstein &amp; Co. of New York, New York published the song. Artist Albert Wilfred Barbelle designed the sheet music cover. It features a mother saying good-bye to her soldier son. It was written for both voice and piano.
In the song, a son is comforting his mother before he heads off to war. The chorus is as follows: 
"Cheer up, mother, smile and don't be sighing"
"Dry the teardrop in your eye;"
"We'll come back with colors flying"
"After the war clouds roll by," 
"Homeward bound then"
"We'll come sailing, mother."
"We will win out, never fear;"
"Dad came home from fields of glory,"
"Maybe I'll repeat his story,"
"So cheer up, mother dear."
The sheet music can be found at Pritzker Military Museum &amp; Library.
