Can you guess who the sharp-dressed young man in this yearbook photo is? Let's get you started with some basic facts. He's a drummer, born on December 20, 1945, and a founding member of one of rock's most successful bands of the '70s.

Now in full disclosure, this is not exactly a yearbook photo, but instead a picture from his First Holy Communion at Catholic school. Doesn't he look cute preparing to receive the Eucharist for the very first time?

What else can we tell you? He studied his instrument under the tutelage of his idol Gene Krupa, his pre-fame band was called Lips, and he is a gun enthusiast. Any more information would just give it away. And where is the fun in that? Think you got the right guy in mind? Find out here!
