Listening to him right now on Sirius Friday Night Opry, spoke a bit about Jimmy now singing Highway 40 Blues.
Love Ricky Skaggs, and that song is one of my favorites. If the history of country music interests you, there’s a fantastic multi-episode documentary on YouTube, BBC-produced, about the history of country music. It starts with The Original Carter Family and Jimmie Rodgers, goes through the Shania and Garth thing, and up to Gillian Welch and the people who are steering clear of Music Row in order to protect the integrity of their music. It’s a bit out of date on the end era, but the beginning and middle are fantastic, as BBC documentaries are traditionally when they don’t try to politicise them. It also touches on bluegrass ( I believe that “O Brother” was big when the documentary was made). It was cool to recall the era of the neo-traditionalists-Dwight Yoakum, Randy Travis, etc.
