the poster of this video claims it was made in Cleveland the day before Otis Redding and most of the
Bar-Kays died in a plane crash.

Here's an interesting juxtapositioning of that video with a bunch of 70s soul schlock ballads:

One man's opinion -- soul music took a very bad turn in the early 70s, and disco was the death
knell. The raw passion and excitement of James Brown, Otis and early Aretha blow the doors off the
too-slow, too-sweet fluff that came later.

RIP Otis Redding.
