As regards the music for the later stages of the RWC, I found this press release today:

"Four premier Kiwi singers have been confirmed for the anthem singing roles at the two semi-finals of Rugby World Cup 2011 (RWC 2011).
Elizabeth Marvelly, Nick Afoa, Ainslie Allen and Jonathan Lemalu will sing the anthems at the two RWC 2011 semi-finals on October 15 and 16. They join Hayley Westenra and Will Martin, who were previously confirmed to sing the anthems at the Final on October 23."

So bye-bye the NZCF anthem choirs. Actually, I quite like Hayley Westenra, who is a sweet girl and I've heard Jonathan Lemalu in concert and he is awesome.

Go Wales!
