@Bobbiepin Thank you for your kind wishes. Your wedding sounds ace! Did you survive the Israeli dancing?! My brother genuinely thought he was going to die when he was being flung up in the air on a sheet.....because he's been at weddings holding the sheet, and hearing it start to rip! 
DH and I were at a United wedding a couple of years ago, and after the bentsching the band played Hatikvah, and then everyone stood up for the national anthem. DH was a bit bemused, asking 'why are we singing G-d save the queen at a wedding?!' I'd never really thought about it as weird - I had to think of why it was we did that! Similar reasons why there are prayers for the Queen and Royal family in the Shabbat service along with prayers for Israel, was my guess.
YY on the Seder - it's basically Jewish Xmas! There was a great Seder thread in Chat, equivalent of the Xmas threads around December
Someone posted this, which cracked me up:
