I blew it in a couple spots with the ABC. The "B" leading tones in lines 1 and 4 should be B flats. Here's the corrected ABC:

X: 1
T: ?
M: 2/4
L: 1/8
K: Cmin

C | CGGF | _EDC C/2D/2 | _E_ED_B, | C3 C |
CGGF | _ED C/2D/2 | _E_EFF | G3 G |
cGGG | F_ED F | _BFF_E | D3 C |
CGGF | _EDCD | _E_ED_B, | C3 ||
