After many years of teaching, playing, and singing in California he married a third time, and with his wife relocated to Atlanta, where he performs on banjo, guitar (many styles, including jazz), ukulele, voice, and other instruments and co-founded the Frank Hamilton School[4] in 2015.

His father, Frank Strawn Hamilton, died before his son's birth; he had been a California socialist philosopher, genius street-corner orator, and mentor to Jack London.

He began learning and collecting folk songs, with a special interest in the music of the American South; he spent much of the late 1940s and early 1950s traveling there, performing in bars and on street corners.

[8] Second Half, which follows the class lessons, is essential to the Old Town School method: both teachers and students sing and play together at their own level, and especially talented men and women are invited to perform.

Bob Bakert, a friend of Frank's, volunteered to serve as Master of Ceremonies for the memorial concert for her, at Steve's Live Music in Sandy Springs.

Concerned for Frank's well-being, and having heard of his interest in starting a second folk music school in Atlanta, Bakert suggested helping him achieve that goal; Hamilton responded positively.

Under the current leadership of Hamilton and Maura Hill Nicholson the school now meets in eight-week sessions at the Gillespie Building at Decatur Legacy Park.
