A Song in the Road Bed?

I talked to Mr. H earlier this evening. He was in the lobby of his hotel, waiting on the other guys to come down so they could go to dinner. There was a television tuned to a local news station that was running a story about a roadway that played music. That's right: a musical road. The roadbed was cut with grooves so that as you drove over it, you generated the "William Tell Overture" (the Lone Ranger theme). Wait a second...
I'll be right back....






I found a video of it.



Here's the same tune with words you've probably heard all you life, just never delivered this way.
