I think this from the SPR ING quiz in aid of the Romanian Aid Foundation this only mentioned on here on Monday and doesn't finish until 20th June. Keep searching and if you don't find the answer ask again in June.
The quiz details are in the round-up thread if anyone wants to send for it - Mixture of 60 questions - 30 answers containing the letters SPR or ING and 30 questions on locations in Wales and and songs by Welsh singers/groups.
Good luck
