I don’t know who that guy is by the way. He’s just a guy.
By the way, in case you’re wondering, that song is “All the World” by Kansas, whose title is really accurate. It starts as a song about piece, it then suddenly changes to a hard guitar riff (assumably about war), followed by a sudden transition to a love song, which then then transitions into a song about death. It ends with a message of hope. It’s an awesome song from an awesome album, but I could easily see someone getting carried away singing the love song part of it.
