Think of it this way...

What is the one thing at your wedding that no one can avoid?  Well, you can not have the chicken, you can show up late and miss the ceremony, you can not be in the limo, you can also avoid the wedding cake.  The DJ though, is unavoidable.  His/her speakers help to fill up the room, or empty it.  Whether it is grandma or your college friends a good DJ should get people dancing.  A great DJ did his homework in advance and makes everyone enjoy a day all about you.  A great DJ keeps reminding people why they are there with songs and references that are about you and your new spouse. 
Make your wedding sound like your wedding and everyone will know it was the best wedding they were ever at!  If this sounds like what you are looking for for your wedding and guests call 847-406-3535 for Fun Times DJ.
