Although Blind Willie Johnson recorded only Gospel songs his slide guitar playing is drenched in the blues.
All his slide songs are played in open D tuning (DADF#AD) but I arranged this one for the 4-string cigar box guitar tuned to GDgd.
You can find the neat poster at bluesimages.com (plus a lot of other cool prewar blues stuff).
The cigar box guitar was made by Fuzzy, who lives in the heart of Texas, where Blind Willie played the streets.
check him out at his channel where he demonstrates his cbg’s (available at ebay)
Here’s a link to the original by Blind Willie Johnson
