If we got it right, our speeches went something like this.......
My brother (or your dad etc) made the 1st speech. His was VERY funny, espcially when he toasted us (he actually had toast on string and hung it round our necks!!

)
He then toasted us!
Then Mark stood up and thanked Iain for us, then gave out thank you pressies, thought of people who couldn't be threr and toasted the bridesmaids.......
then best man thanked Mark on behalf of bridesmaids and told funny stores, read message etc.
Marks speech wasn't very long, he said how beautiful I looked, thanked parents etc (if they helped) and thanked everybody for coming to help us celebrate. It wasn't a humorous speech, just a few mintues to reflect on the day
Sorry this wasn't much help, but your h2b won't need to say a lot, it's more left to the father/brother and best man!
Lo xx
