At several recent conventions CALLERLAB ran a session titled “A Visit With the Legends”. In each session several well known callers talked about their early days and related “war stories” about events in their calling careers. This article has direct pointers to those recordings.
This podcast hosted by Dayle Hodge and Barb Jarvis ran for about 40 episodes in 2011 and 2012. In each episode Dayle and Barb would interview callers or notable people in the square dance community about their lives and their views on various aspects of the activity.
