“You’ll Grow Sweeter (As The Years Go By)” is a popular sheet music piece composed by Haven Gillespie and J. Fred Coots in 1934. The song features a romantic and sentimental melody with lyrics that describe the enduring nature of true love over time. The title phrase, “You’ll grow sweeter as the years go by,” is repeated throughout the song, emphasizing the idea that love only grows stronger with age. The piece was popularized by various musicians and singers, including Rudy Vallee and Bing Crosby, and remains a classic of the Tin Pan Alley era.
This piece is unusual in that is marked “PROFESSIONAL COPY. This Copy is intended for the use of PROFESSIONAL SINGERS ONLY, and any one found selling or exposing it for sale is liable to a fine or imprisonment, or both, and will be prosecuted under the copyright law by THE PUBLISHER.” Evidently, it was used in some type of professional performance. Since the music is in the public domain and the publisher is out of business, it can now be sold.
