"Grub Springs" is an old-time breakdown in A Major played in standard or AEae fiddle tuning. The parts are played AB (Silberberg) or AABB (Phillips). This is perhaps the Alabama fiddler Charlie Stripling's version, from a 1952 AFS recording made by Ray Browne. Stripling played the tune in standard tuning (Kerry Blech says it "sort of vacillates between the A tonal center and the D tonal center"). I got the banjo tab from Adam Hurt at Midwest Banjo Camp. Grub Springs Branch is the name of a stream in Monroe County, northeast Mississippi, near the town of Caledonia. It was printed in Phillips' Traditional American Fiddle Tunes, vol. 1 (1994), Silberberg's Tunes I Learned at Tractor Tavern (2002). It was recorded by Rafe Stefanini on Glory on the Big String, Alan Block on Alive and Well and Fiddling and various performers on American Fiddle Tunes (1971).
