Plain 12-bar blues, with this little riff played a few times as an intro, and wherever there is an A:
Ab : . . . : . . . |-------5-----3-----------|-------------------------| |(2)----------------------|-5-----3-----------------| |(2)----------------------|-----------5-------2-----| |(2)----------------------|-------------------------| |-0-----------------------|-------------------------| |-------------------------|-------------------------|
Or with this variation:
A : . . . : . . . |-------5-----3-----------|-5---3-------------------| |-------------------------|-------5---3-------------| |-------------------------|-------------5---2-------| |-------------------------|-------------------------| |-0-----------------------|-------------------------| |-------------------------|-------------------------|
That's just about all there is to say.
A                                                          [riff]
Wonderin', I'm Wonderin', when will my swamp catch on fire
    D                                                   A  [riff]
I'm wonderin', I'm wonderin: Is my swamp gonna catch on fire
E                            E7                A           [riff] x 2
Sittin' here lookin' at that old bad telephone wire.
Well, I'm goin' to Las Vegas, goin' by the evening sun
I'm goin' to Las Vegas, goin' just as fast as I can run
Gonna win some money, give it to my hon.
