EDIT: My original question was regarding songs like those of Bad Company like "Feel Like Makin Love." I didn't know about the controversy with the Lynyrd Skynyrd song, and that is what the thread turned into a discussion of. UPDATE 1: The song has a D tonal center (to my ears). It uses the chords D, C, G, and F. Or some variation of them. UPDATE 2: Blues Scale in "D" sounds right. UPDATE 3: I should have used Bad Company's "Feel Like Makin Love" as the example for the question. Neither song uses the V chord.
