If you are really interested (or anyone else is interested), George M. Cohan was 22 and Noël Coward was 25. Moss Hart was 25 when Jonica, for which he wrote the book, was produced on Broadway. He was still 25 when Once in a Lifetime opened a few months later. There have probably been others 25 and under, mostly in the fairly distant past when people often got started younger.
EDIT: Lorenz Hart, Richard Rodgers, Cole Porter, Oscar Hammerstein . . . all of them under 25. |
