Pavarotti duet - Panis angelicus

Accompanying a student's grade 5 singing exam last week I was reminded of one of my favourite youtube vids: https://youtu.be/jt1WeSN0sm0?feature=shared - (Panis angelicus by Cesar Franck). I can't find the interview but if memory serves Papa Pavarotti once told him "imagine what you could have achieved if you'd had MY voice"... really hope that's not a false memory 😂😉
