The serious earworm is when you put into words the signature guitar solo to yourself. It sounds something like this: "deer to deer, deer, deer, deer, deer, deer, diddly, deer, deer, deer." Or something like that.

It's total southern nuthouse territory. But that's Lynyrd Skynyrd's "Free Bird" for ya. Earworming it this very second. And this bird cannot chay-a-yange! Lord help me, I cannot chay-a-yange!

As for the charts, the 1974 song only peaked at No. 19 on Billboard.

No. 19? Just goes to show that the classics aren't always No. 1. But try to stop humming it. That bird you cannot change.
