There are at least three DJ's going by the name 'Casper', and strangely enough two of them have roots in Chicago; one is drum and bass DJ, the other is famous for his 'Cha Cha Slide' single.

1. DJ Casper (real name Wille Perry) is a Chicago based DJ who had a number one hit single in the UK called "Cha Cha Slide". MC Jig also did a version of this song, but the DJ Casper version was far more successful.
