This gospel group, the Golden Echoes from Franklinton, North Carolina, is a different entity than the Golden Echoes from Cleveland, Ohio. Several Landis men are in this group including "Big John" and Claude.

A man named Tom Davenport made a documentary named A Singing Stream, "a chronicle of four generations of the Landis family, members of the famous Golden Echos black gospel music group from rural Creedmoor, N.C". The documentary is here: https://www.folkstreams.net/films/singing-stream.
