I was asked by two good friends 2.5 years ago. It was a blast and made for a great memory for both.
I sent a few drafts to them of what would be said and got approval of all as it is their day. All the pressure of 100 or so folks watching you definitely made me slip once and call Kevin and Shelly Shevin and Kelly. All laughed and it was great, but fairly nerve racking for a few minutes.
Do it, they will love it, you will remember it and it will be that much more special.
PM if you want more info.
