Let's Get It On

This unusual promo release has "Part I" of the track in Mono on one side, and a Stereo version of the entire track (listed as "Parts I & II") on the other. It's definitely worth having the entire 4:40 recording, since it's clear from Part II that this is more than your typical soul instrumental once some lady comes to the mike and starts whispering "Baby!", Pillow-Talk style. :-) The whole thing is a terrific celebration of Marvin Gaye's masterpiece.
