I like it - i think it was fun, light hearted and cheesy Made me smile anyway!
As others have said i think if it had "normal" voices it would then take the fun out of it...
You could almost make a mini series of them out of it - the first one being at the sisters wedding with the bad DJ talking on the mic (with a computer generated voice) playing Agadoo or something with the main characters in the back of the room - to the second episode in the restaurant right the way through to the wedding and their night with you as DJ
