This is not a Disc Jockey Service. It is two people Bud and Alex Becker. The person you speak with on the telephone is the person who will be at your function. The system is completely computerized with over 50,000 MP3 music files in the hard drive covering almost any musical selection you can name. Remember a wedding is something that can not be "made up or refunded!" It is not a matter of money, it is a matter of that "special day" which can not be repeated. Pages of references are on the web site.
