It's also possible that someone on this list never saw

either one of them, and it's highly possibly that this person loved both clips!
The guitar solo in the first clip sounds much more like Eddie Lang than Django. This is one small area where I happen to have a little bit of background knowledge ... I suspect there are countless other period authentities I didn't pick up on, but the net effect is very convincing.
The singer in the second clip sounds like a native speaker from the U.S. That can be one stumbling block for European performers, if they want a convincing sound in every respect ... with a long and proud history going back at least as far as Django with that falsetto singer who sounded like he was reading phoenetically off a sheet with no comprehension, but I enjoy his singing anyway.
