Finally I can offer some answers
Lamb outhalf for London Irish
There is an Isle sung in Limerick at rugby matches
Ben and Jerry O'Connor play hurling for Cork and are twins although toons also fits?
Simpson is OJ Simpson
Isle, Rugby song sung in Limerick
Lamb, Ryan Lamb plays at No.10 for London Irish
O'Connor, Twins on Cork Hurling team
Ursa, Racehorse and Star, Ursa Major
Simpson is correct. OJ was called Juice
Thanks guys but I think I'm wrong if these are the correct answers to some of them
10 down "The special ones number 9". I think that's ronaldo. If it's correct then isle and lamb don;t fit ??
Now I'm really puzzled :)
