One more thing..."We Gotta Get Out of this Place" was the first time I'd done a cover, so I wrote to the Harry Fox Agency and asked what kind of license I needed to use it in a YouTube video. They basically said they don't deal with that, but some publishers have arrangements with YouTube that allow posting of videos containing copyrighted content. Of course, if I sold a CD with the same thing, that would be a different story.
Their bottom line was "post the video and see if they ask you to take it down." Uh...okay.
BTW being in the publishing biz and having done multiple albums over the years I know a hell of a lot about fair use. There are four main criteria for determining fair use. You can search for details (and
this site is particularly good), but the main tests are:
1. Not used for commercial purposes
2. Transformative (i.e., adds value and creates something new vs. verbatim reproduction)
3. The amount of the work that's used
4. Whether it diminishes the work's value or deprives the owner of income
If you post a song that's not yours and add a video, you won't pass test (3) and a court would likely reject (2) because you have not done anything transformative with the work itself, merely overlaid a separate video.
The places where you can almost always get by with fair use is excerpts for commentary or review, parodies, and dissemination of small amounts of educational material.
