SwingDJs

Paul and Sharon's webpage has always been a good source of music info. His album recommendations cover some of the better groovy swing music out there. I hadn't surfed there recently, but I just found that they've added even more stuff to it. An "artist of the month" that talks about the artists and provides some music recommendations. Its worth checking out.
Here's the page for Gene Harris:

His list of 400 danceable songs is now online, too.
