Conversation with some guy I see on IRC sometimes, turns out his brother is the vocalist for Keep Of Kalessin.
[D3ads] holy fuck, Megadeth playing in Nottingham in Feburary :D
[Pampers] i think my brother played in nottingham as well when his band toured europe
[D3ads] what band?
[Pampers] keep of kalessin
[D3ads] I saw them with Enslaved, they were brilliant
[D3ads] Some people weren't so impressed though
[Pampers] my brother -> vocals
Small world indeed and no according to him, Thebon and Wizziac are not brothers :P
