12 Bar Blues

I composed a little 12 bar blues called "Why don't you give me any money". It's in C (mixolydian) and it's a slight variation of the standard blues scheme.

The chords are (with one measure per chord):
C7 | F7 | C7 | C7 |
F7 | F7 | C7 | C7 |
D7 | A7 | Ab7 | G7 |

I think I will play it on the 25th in the Woodside.
