When it comes to emceeing duties, I'm always more than happy to make basic announcements and whatever else the client wishes - leading the boquet/garter toss ceremonies, games, etc.
Inviting the bride & groom to the dance floor
Introducing individuals who will be giving toasts
Helping to direct guests from one area of the venue to another
Announcing the cake cutting
Gathering people up for the boquet and garter toss
Wedding Games (musical chairs, the “shoe game” etc). If you would like a wedding DJ that handles these types of items, I don’t think I would not be an appropriate choice for your event.
Leading group dances or lines dances (Cha Cha Slide, Electric Slide etc). This is definitely not something that I would be able to facilitate. I can certainly play any of those songs if requested (on a side note, those types of songs are normally on my default “do not play” list unless specifically requested by clients), but I’m not going to be out on the floor (or on the microphone) instructing the crowd on the dance moves.
In order to make sure that I address all the important items a client would like announced yet minimize any unnecessary chatter, I always ask my clients to specifically note the items that they would like announced on their schedule, so there is no speculation on what should (or shouldn’t) be announced.
