It seems Jackson didn't care the number of bars in his decision to play Blues or a ballad. For instance, Love Sick Blues a song of 8 bars but he didn't play in his ballad style but his Blues style. In case the number of bars and form of the theme is what supposed to be the thing that defines Blues than Jim Jackson doesn't seems to care, whenever he want to play his Blues licks, he does it anyway.
Who said 12 bars defines Blues?
