Could the compiler please confirm that the letters in question 37 (i foul bean stuffing) are correct, as no anagram solver will come up with an answer, and a possible Welsh town doesn't fit, unless there happens to be an alternative spelling!
clutching at straws here but i can only get near the anagram with BLAENAU FFESTINIOG - but this would require your letter F to become letter E - only guessing as i don't know the 'quiz' - if you are thinking along these lines, then maybe you are correct - anyway good luck ?
