Elvis sang "Good luck charm", but I can not see anything that would help.
Amongst things he did not want, were, rabbit's foot,
Silver dollar, lucky penny, four leafed clover and an old horseshoe.
I have not been much help, Fogram.
I think "leek" is correct though.
There is a town in Staffordshire (I think!) called Leek which is known as Queen of the Moorland.
Good luck with the rest of the quiz!
