Alan Lomax- THE LAND WHERE THE BLUES BEGAN on YouTube

I had no idea Lomax's The Land Where The Blues Began was on YT! 

I've got it on vhs and have seen clips on YouTube. 
C.R. Humphrey from Old Gray Mule sez,  
"In my opinion, this is the best blues doc out there bar none...if'n you haven't seen it, set aside an hour some evening it's for damn sure worth watching." 
I'd say it's a three-way tie with Deep Blues and You See Me Laughin'. 
All three are essential viewing for blues fans.
