Ask them to poll their Guests and email you a list or take requests that night. Most will have an Ipod or Phone with them and will ask you to play a track or two. DOn't buy to much in advance, because what you may buy they might not want
Tom, don't beat yourself up. I have yet to play or even have a request. I think it's very regional, here in the Northeast it took while for the Cha-Cha Slide to become big here. I DJ everything from Weddings to Schools.
I am back in PA til thursday morning. I am staying in Valley Forge / King of Prussia while my wife is working at her corporate HQ. I was looking to connect with someone from the area. I was thinking of going to Harrah's in Chester PA on Wednesday.
