For an events on this scale, the commentators have lists with name and function etc... of each guest. The royals, but also celebrities, members of the Parliament and from each political party, heads of state, ambassadors, Governors General and prime ministers. We'll see the arrivals, the people take their seat inside the Abbaye, the wedding itself, the departure and the procession, the balcony kiss and the appareance of the whole royal family, the flypast, the arrival of the guests inside Buckingham Palace (I just found the arrival of the carriage of Charles and Diana inside the palace courtyard and the arrival of many guests, I had never saw these photos before). We can hope we'll see cameras inside the many rooms where QEII will receive the dignitiaries because things change and the B. Royal Family knows it more than any Royal Family.
This event has generated too much passion and madness throughout the world for the royal family not to use it as much as it can. To capitalize on this young couple, I think it will open the doors of BP. Besides the reception offered by the Prince of Wales in the evening is stamped "private party", so we can hope that the Queen's reception will allow, versus, the cameras of the BBC to have access to the reception including the wedding cake. I can not believe that in receiving so many heads of state, Governors, Prime ministers and Royalty, the Queen does not allow cameras inside BP. Then, in previous marriages, Internet did not exist. The information could not be relayed instantly like today. And there was no major marriage for 30 years in the UK. Edward's marriage was not a major one and it took place shortly after the death of Diana. That of Charles and Camilla was a remarriage that has spilled too much ink. Marriages in Spain, Denmark and Sweden are all marriages of the Internet era, and information transmitted instantaneously to millions of people simultaneously. The British royal family has not had the opportunity to do otherwise.
I want to think this times they are going to surprise us. I hope !!!
