Which rock song has "calibration" in first line of its lyrics?

Can you guess? Think back for a moment or two. It's a few years old now. I always thought it might have been good to blast it through the sound system at the opening of the exhibit halls at ISA Expo or one of the many other tradeshows and user groups that we cover each year. However, it would be hard to find a powerful enough boom box for a freelance effort in this iPod era. Oh well. Anyway, it's quite an uplifting tune. Even the opening guitar riff should clear some cobwebs and recharge some mental batteries on this Friday afternoon. Give up? OK, here it is: http://www.youtube.com/watch?v=13mYOXESv18
