@shun -- Rick and the FAME Gang actually produced the first two or three Osmonds albums, as well as the Donny Osmond Album. "Flirtin'" from that album really showcases that sound:

It's astounding how many hits have come out of FAME studios and Muscle Shoals Sound. My sister had classes at The University of North Alabama with Rick's sons, and with the kids of a couple of the Swampers.
I live about 40 miles east of the Shoals, but everybody knows someone who knows someone who worked there or something. LOL.
