Yours fits the clue, Till- but I don't know any songs of that name.
The only one I know with 18 in the title is "18 with a bullet" but it can't be that
I can see where the 'LITTLE WORD' comes from, judith, but can't see how "between 17&19" gives the word ONE
I am also not certain that spoken --> WORD. Could it be SAID/TOLD etc?
Or could this be a reference to Questions 17 and 19 in this quiz?
Just seen dannyk's 18 Wheeler suggestion. There is a song called Roll on Eighteen Wheeler, and the spoken reference could mean 'having spokes', as a wheel does. I'm not sure about the 'small' but I think it's the best answer so far
