We used Ivan as well- and he was phenonimal!  I gave him a very detailed list of what we wanted played and he played every single song (that I can remember!)  And we did a bit of a remix for our 1st dance- and he did it just as I asked.  He got all of our Bridal Party introductions right and our other special dances.  Our guests were very impressed with him.  He came up to me at the end of the night and asked what I wanted for the last song.  (we had him for 4 hours)  Our reception was a blast and I had no worries or stress regarding our DJ-- he kept telling me, I got it-- it was all under control-- and it was.  Thanks!!
