Here's an underrated band/song. Molly Hatchet - Fall of the Peacemakers.
It's been called a lesser version of "Abraham, Martin and John", but I think that's an unfair and unfitting comparison.
This is good old-fashioned southern rock. Crank the volume up to 11 and enjoy - especially the chord right after the end of the singing and at the start of ~4 minutes of jamming. My wife hates this for some reason, so I only crank it up when she's gone.
