A Tenor, an author, and an actor. Can't say I'm a huge fan of any of their work--but they were all well-known and well-liked. I'm reminded of a recording I heard of Luciano Pavarotti singing along with the Sepultura song "Roots Bloody Roots." You really haven't lived until you've heard the death/thrash metal and opera hybrid.
Actually, yes you have. It's terrible.
EDIT: But just in case you're curious, here it is:
Someone must have just cut in video footage of Pavarotti singing something else when his part comes in, and it's kind of cheesy. But really, the whole thing is insane. Especially in the end, when Max Cavalera--Sepultura's Brazilian vocalist--imitates Pavarotti.
More satisfying: Pavarotti and James Brown:
It fits better. After all--it's the Godfather of Soul. And the . . . most famous Tenor.
