Watch the Someday Baby Solo online guitar lesson by Jeff McErlain from Essentials: Advanced Blues Soloing
Here's a classic 8 bar blues tune in a standard form. I first heard the Freddie King blues classic "Someday After a While, You'll Be Sorry" on the John Mayall record Hard Road with Peter Green on guitar. I came to the blues, as many of us did, via the British blues rock bands like Cream, John Mayall, Led Zeppelin, and Fleetwood Mac. So, the playing is a bit more aggressive than the American influences who came before them. This is an 8 bar form that you should memorize, as it's a nice change from a standard 12 bar blues.
