Happy Birthday, Doc Watson!

Usually. I frown on double posting, for this blog, because so many ideas, just need to be digested, for a day or so, by my readers.  But... today, I will do a double post, and say Happy Birthday, to the late, great bluegrass guitar legend, Doc Watson.  Here he is, playing with another late, great bluegrass picker... mandolin master, Bill Monroe.  They are playing the tune, "Sally Goodin" at a concert, filmed in 1990.  Check this out.
