Just wondering as I have harley ever seen another first dance and I always use the same thing. Goes along the lines of:
Good evening ladies and gentlemen, Can i have your attention (pause), please be upstanding - welcome to (venue) for (bride and grooms first names) wedding. I hope you have had a wonderful day. my name is Toby and I am your DJ for the night. Are you all ready for a party? (They normally say yes!).
Well before that happens its now time for first dance (pause)
so would you please give a big round of aplause (I always have them out the room if poss) for your bride and groom. (pause)
Mr & Mrs .... (Surname).
Here is a half decent one Not quite like above as I adapt it to suit the venue and crowd.
