Charles Tobias was born on August 15, 1898 in New York City. He grew up in Worcester, Massachusetts with brothers Harry Tobias and Henry Tobias, also songwriters.
He started his musical career in vaudeville. In 1923, he founded his own music publishing firm and worked on Tin Pan Alley. Tobias referred to himself as "the boy who writes the songs you sing," a title which he richly deserves.
His credits include "Merrily we roll along", "Rose O'day", "Those Lazy Hazy Crazy Days Of Summer", "Comes Love" and "Don't sit under the Apple Tree (with anyone else but me)."
He co-wrote the 1933 to 1936 Merrie Melodies theme song "I Think You're Ducky" with Gerald Marks and Sidney Clare. And, he later co-wrote the 1936-1943 Merrie Melodies theme song "Merrily We Roll Along" with Murray Mencher and Eddie Cantor.
Immediately after Pearl harbor, he and Cliff Friend wrote and recorded "We Did It Before and We Can Do It Again" on December 16, 1941. The song reminded the United States of World War I, and confidently predicts "we can do it again."
