Attendees Bust a Move at the Republican National Convention

— -- Delegates danced with fervor tonight at the Quicken Loans Arena in downtown Cleveland, as a house band warmed up the crowd prior to a slate of speakers on the opening night of the Republican National Convention.

The band was followed by endorsements of Donald Trump by two veterans of reality television, Willie Robertson of "Duck Dynasty" and Scott Baio of "Scott Baio Is 45...and Single" (and, of course, "Happy Days").

The RNC runs through Thursday.
