Here is the late John Hartford playing Gentle On My Mind, a song he wrote in 1965, which has been recorded by many folk over the years including Glen Campbell who brought it to promenence.
John Hartford was an American original. He was a musician, songwriter, steamboat pilot, author, artist, disc jockey, calligrapher, dancer, folklorist, father, and historian.
John Hartford won Grammy awards in three different decades, recorded a catalog of more than 30 albums, and wrote one of the most popular songs of all time, Gentle On My Mind. He was a regular guest and contributor on the Glen Campbell Good Time Hour and the Smothers Brothers Show. He added music and narration to Ken Burns’ landmark Civil War series, and was an integral part of the hugely popular O Brother, Where Art Thou? soundtrack and Down From The Mountain concert tour. But that hardly explains John Hartford.
