This fellow talks about Charlie Patton and 13&1/2 bars about 3/4 of the way down the page:

Beginners blues/boogie/rock discussion
Sophia The 3 bars, F7 C7 C7 are the simple body of the tune. The 2 bars below are to be substituted for the last 2 bars of C7, a classic ending phrase. If you play those triplets over a C7 chord however, it sounds terrible. Fine, with just the bass notes. The phrase implies a chord progression, and to actually see the tonality play, C7 under the first triplet, F#dim7 over the second, Fm6 over the third, then C, F, F#, G in the last bar, before returning to the top, or playing a final ending chord, which could be a simple Cmajor triad, or C9 for a more jazzy sound.
Well, I decided to compromise and just practiced the lesson with the sequences shown in the top line. That also means I'm just about done with the lesson (sorry WieWaldi) 
although I want it to sound a little more smoothly before I record it and continue to the next.
Oh definitely not skipping it. You may remember (though hopefully not) the dreadful rendition in lesson 4.
But somehow, my ears don't like it very much following the G7 F7 sequence we're playing in this particular lesson.
Yeah, I know, bloody beginner and already picky 
You're too kind, lol!
and I'm a

)Oooh lovely!!!!! Hit the Road Jack - one of my favourites! VERY well played and I can hear some very tricky fast bits too. I love all the variations and your new pro drummer. I hope you pay a good salary...
And you know who won the race between the

right?
(now I must get some turn-around practice in which will delay my next video by at least 3 minutes to get that perfect... yeah I wish!!!)
and 
. Do you think this counts as duet?Of course! Next he'll demand equal billing - not shoved in the corner while you shine on the big screen
I am trying to think of an ending of my own imagination to this lesson. Of course my brain can create very complicated nice sounding licks, then I stare at my fingers and nothing happens 
But maybe I can come up with one that is simple enough to play and that still counts as my own, not 100% included in the lesson...
Same here. I can hear some very nice licks and phrases in my head. But my fingers can't tell the keyboard.

If can - do it. I would love to hear it.
You will love lesson 12, then. A very simple left hand and the right hand is just jamming around.
6 days later
Well, lesson 5 is done. It took a little longer because it's HOT out here (as in: Canada hot, not Death Valley hot, but STILL). So, without further ado, short but sweet and with a non-spectacular "custom" ending (just the same lick in another setting and a final chord that I made up really):
Onwards to lesson 6!
Wait, WHAT? After all my lessons and still only a BLOODY beginner???? That's not fair...

Sophia 
Well done! And it is interesting - you played both the high chords of G7/F7 with two keys. I did them with three (B F A and C Eb G). You got the notes from his sheet-music, right? I did figure the notes out by his video only, and here he played an extended version (at least once - and I am sure I wanted to stick to the example with the most keys, haha).
Still - I am missing the mother of all turnarounds (video at 12:22)...
Wait - where are the kittens? 
Oh, yes I played the sheet music version:
One of the kittens is hidden in the video - see if you can spot him But you are right, I didn't play the mother of all turnarounds because I wanted to come up with my own version (much worse, but entirely my own, therefore much worse)
Yes - differences. The biggest thing don't like about his sheet music is the layout. Line breaks and page breaks when it really hurts. I always opted to have exactly two bars on one single line to see repeating patterns easier:
C7 - C7
C7- C7
F7 - F7
C7 - C7
G7 - F7
C7 - C7
I don't like the auto-alignment with 3 bars on a line while 2 or 4 make more sense in terms of musical structure.
Oh - and for the black keys you have always two possibilities, how to notate them. Either with a # or a b symbol. I tried to always use the version that does not require a natural sign later on.
I tried to figure out a rule for music notation in the other forum, but all the answers did not make any sense to me. It was something with harmonic or tonic, and I didn't understand it. And also today, I don't get it yet. Ask me in two years again. Maybe my music theory will be better than - haha.
Oh - yes. A kitten (Lionel/Sandy?) hiding on the left leg. Let me tell you what happened: You played really great! Your little tiger has no complaints about it, and didn't see the need to correct you on the fly.
Yeah I don't like his sheet music either. And I think reading a blues would raise a lot of eyebrows, so I prefer to learn it by heart and pretend I was improvising
btw, my version for the bloody beginners:
