Another banjo-centric resource.  Don Zepp has created many, many videos of old time tunes played on banjos from his long-since-gone music store.  The tunes are the ones we play a lot and make a great reference library.  His website is also vintage!  But it has even more resources and information.  There’s a Facebook page, too, and a blog.  Don’t expect a lot of new content but, Hey!, it’s old time!
