This Rob Bowman character, who I got that last quote from, turns out is the world’s leading Try A Little Tenderness scholar, as far as I can tell (by virtue of writing one essay about the song). This makes him pretty much the coolest. If I were an ethnomusicologist, instead of a half dozen blog posts, I’d do something like “The determining role of performance in the articulation of meaning: the case of ‘Try a Little Tenderness’” which Bowman wrote for a book called Analyzing Popular Music. It’s a little heavy on formal differences that went over my head, and a few pages are missing from the Google Books version, but it’s pretty cool: He compares the recordings of Bing Crosby, Franklin, Cooke, and Otis and has a bunch to say about it. This also includes the “motherfucker” quote.
Important bit of information I learned: there are two outtakes of Otis’s version, and at least one of them might be available somewhere. Hearing this would be pretty fantastic, so far I’ve only got 30 seconds.
