[1] Barrett discovered and promoted Frankie Lymon & the Teenagers, the Chantels, Little Anthony & the Imperials, the Valentines, and Philadelphia's the Three Degrees.
As an artist, he is most famous for co-writing (with Leiber and Stoller) and recording, as Richie Barrett, the song "Some Other Guy".
He recorded "Some Other Guy" in 1962, a tune modeled on Ray Charles' "What'd I Say" and was assured immortality, if not a hit single, following cover versions performed by the Beatles and other Liverpool groups of the time, including the Searchers and the Big Three.
A clip of the Beatles performing the song at the Cavern was shown on a regional television program screened by Granada TV in the north-west of England in August or September 1962 shortly after the band had fired their previous drummer Pete Best and replaced him with Ringo Starr, and this low-quality footage has been included on many videos and DVDs since that time.
In 1998, Ben Vereen portrayed Barrett in Why Do Fools Fall in Love, a film biography about Frankie Lymon.
