Over the years, we've shown yearbook photos and have asked readers to guess which rock stars they turned out to be. Some of these musicians' looks changed dramatically since their school days, while others are more instantly recognizable.

Here we present a number of these yearbook pics in one video montage. In this video, we feature yearbook pictures from Kurt Cobain, Tommy Lee, Axl Rose, Nikki Sixx, Fred Durst, Jacoby Shaddix, Chester Bennington, Chad Kroeger, Trent Reznor, Wes Borland, Mick Mars, Mike Shinoda, Zack De La Rocha, Mike Patton and Layne Staley.

Check out the yearbook pics of 15 rock stars in the video above.
