The Ken levigne one? really funny seeing him try not to swear.Aren't they amazing? There's one of an American voice coach hearing Bruce Dickinson for the first time (supposedly first time, Bruce Dickinson is one of the most famous people in the world of music)
One I do like is this fella. Not a reaction so much as an analysis. He has done a few maiden songs now and will be doing more. Nice to watch him realise how cleverly this stuff is crafted.
