Lunchtime progression

I have a short tune stuck in my head. It's legitimate (I'm not humming Avril here) - maybe a theme from a radio program, or something I read with a quintet once upon a time?

I have this in c and 12/8 in my head, but I don't have pitch, so it could be in any minor. If each symbol is a dotted quarter, then:

i-i-i-V-VI-III-iv-V-

How disappointingly simple 90% of the tunes in my head are. In this case, I don't think the original was going to V at the end, nor i again after that.
