Yes agreed! We took my Mum to see the 1000 Voice Choir at the Royal Albert Hall. Oh boy it made the hairs on the back of my neck stand on end, what a sound, nothing like it. I have looked a couple of times to see if they still do it but no joy. Have to make do with my 3cd box set ' best of Wales' which has some real favourites on it.
