'Royal Wedding Watch' Roundup

The Royal Wedding arrives on Saturday. Here are some things to remember when tuning in, courtesy of Royal Wedding Watch.

The Royal Wedding for Prince Harry and Meghan Markle will arrive this Saturday, starting around 4: 30 a.m. ET. Though Americans are not part of the Commonwealth and fought an entire war to be that way, in the more modern era, our fascination with the British Royal Family has only grown. And now we have one marrying an American, which makes this probably the biggest Royal Wedding of our lifetimes. As such, PBS has been airing a series of specials this week to help those who never really took an interest in Royal Etiquette before and has been giving a crash course, co-hosted by ABC's Meredith Vieira and BBC's Matt Baker.

Along with Vieira and Baker, the BBC's Anita Rani and English historian Lucy Worsley have explored different facets of the wedding, including all the usual vendors, from florists to catering to the history of Royal Marriages.

Let's run down some of the major points from the episodes so far.
