I remember reading that only Ireland's Call will be played (and obviously the Italian anthem).
The IRFU protocol is anthem of the state (usually Amhran na bhFiann) followed by team anthem (Ireland's Call). Suppose its all down to whether you consider GSTQ the anthem of Norn Ireland (as opposed to the UK).
I'd personally prefer Danny Boy but I don't think its worth getting worked up about.
