Cover art for Driving Song lyrics by Widespread Panic

This songs basic melody bears an uncanny resmeblance to Status Quo's "Matchstick men",

The Screaming Tree's "All I Know"

and Lenny Kravitz' "Fly Away"

It's a very resilient riff, any other arrangement I would have started hating because I've heard it so many times,...

I'm just curious as to the repeated borrowing of the melody through out the years,

Why has it been used so many times in original material?
