Watch the Someday online guitar lesson by Jeff McErlain from 30 Authentic Blues Grooves You MUST Know
Here is a classic 8 bar blues with some extra changes to spice things up. I prefer doing a tune like this on a gig as opposed to "Stormy Monday" (another jazzier blues) because it is less of a cliche. This tunes is based off of "Someday After A While (You'll Be Sorry)" by John Mayall and The Bluesbreakers. This is from the Hard Road record which was Peter Green's first with Mayall. The tune starts on the turnaround as an intro and has a bridge and a slow 6/8 feel. As I have said many times in this course, it's about adding variety to an evening of blues that keeps it interesting, a tune like this does that.
