What awesome acoustics. Just sensational!

What a glorious hole!

The size of that hole makes me feel horribly inadequate.

As a kid I use to peg pebbles off the water tower near my house. Coolest laser blast sounds ever.

That is an above ground septic tank.

Sounds exactly like Charlotte Church.

I can't help but be disappointed at him having such a crap voice. It would've been spectacular if after all the silly gesticulation and laughing it turned out he sang a mind-blowing, tear-wrenching rendition of the piece.

I just started to learn this song on the piano about a week ago, such an amazing peice, it was originally written for a play and had a different name, but with Ave Maria being the first words, I guess it kind of stuck. For listening purposes check out the the Schubert-Lizst version, mind-bogglingly difficult to play even for the best pianists (many parts have 3 bars to play at once), but exceedingly beautiful to listen to.
