I like to read about the show before I attend.  Here is a paragraph from Ringling.com that describes why they call this new edition of the Blue Unit Circus as "Over the Top."  (If you click any links below, be sure to click BACK in your browser to return to this story.)  http://ringling.com/explore/138/index.aspx

Their Website, Ringling.com, seems to have more "History and Tradition" that I've seen before.  For instance, Who were Barnum and Bailey and who were the Ringling Brothers.  Click the following links to find pages of information:

Barnum:  http://ringling.com/explore/history/ptbarnum_1.aspx

Bailey and the Ringling Brothers:  http://ringling.com/explore/history/bailey_1.aspx

RBBB Circus since it closed in 1956:  http://ringling.com/explore/history/feld_1.aspx

This is the first that I remember seeing a discount on circus tickes if you arrive at the venue via train:  Details
