this is an 8 bar blues with the intro guitar occurring 3 times first one [intro] is different.  
intro; 3 verses; solo (12 bar quick change blues); 2 verses; intro into solo (8 bar blues 1x) out to intro into End.

intro (1 bar guitar; Bass and Drums come in next bar, with pick up, with full 2 bar turnaround I-IV-I-V; 3 bars total)

Oh Lordy, Lord, oh Lordy, Lord,
It hurts me so bad, for us to part, (IV chord lick, quiet stop.) 
Someday baby, ain't gonna worry my life anymore.

You're on my mind every place I go, and 
How much I'll miss you, you'll never know, (IV chord lick, stop.)
Someday baby ain't gonna worry my life anymore.

(next verse uses triplety style chords on guitar part)
Do you remember lyin' on my bed, 
Drinkin' all of that whiskey, talkin' all out of your head, (Bass = IV chord lick, quiet stop.)
Someday baby, you ain't gonna worry my life anymore.

solo (12 bar with quick change, may be 1part loud/1part quiet/1part loud, so 3 times through if done that way) after solo last turnaround, next verse is like first (quite)

Do you remember lyin' on my bed, 
Drinkin' all of that whiskey, talkin' all out of your head, (IV chord lick, stop.)
Someday baby, you ain't gonna worry my life anymore.

(next verse uses chords, Bass does NOT play lick) 
Goodbye baby, I'm leavin' you now,
Don't make much difference, 'cause you never meant me no good anyhow, (Bass does NOT play lick)
Someday baby, you ain't gonna worry my life anymore.
*stop. repeat guitar intro but shorter = 1 bar guitar + bass and drums in, with pick-up, at last half of turnaround = walk-up/pick-up to last half of turn-around = I-V; 2 bars total)

solo (1 time through VERSE [8 bar blues] changes)
*stop. repeat guitar intro but shorter (same as last time) = 1 bar guitar + bass and drums at last half turnaround with walk/pick up to I-V; 2 bars total); after preceding I-V, (same as last except this ends it: like: guitar (intro) break, I-V-I = stop on beat one (1); (not drums, drum fill for that beat) then on beat 2 = #I, 3 = I strum then ring-off, drum fill 2 beats; hit-chord-stop).
