"I'm So Young" is a song written by William H. "Prez" Tyus, Jr., of Cincinnati, Ohio. While still in high school, Tyus wrote the songs "I'm So Young" and "Everyday of the Week" and gave them to a local African-American vocal group called the D'Italians. Once a recording contract with Checker Records was secured, the group changed its name to the Students, and it was under this name that Tyus's two classic doo-wop songs were recorded.
"I'm So Young" has been recorded by Rosie and the Originals, the Del-Vikings, Benjy Ferree and, as "So Young," by the Ronettes, Antony and the Johnsons, and the Devil Dogs. The Beach Boys have issued two different versions of the song, the most well-known being found on the 1965 album The Beach Boys Today! An alternate arrangement recorded on September 9, 1964 was released as a bonus track in 1990.
