JD did an accoustic version of Mystify for some radio station. I must admit, he sounds very good doing it. Almost Michael Hutchence-like. There is no trace of that weird guttural sound for which his singing voice has been so infamous. If he can sing all INXS songs like this, maybe he should get the gig. Why has he been hiding this version of his voice? This doesn't sound anything like the effluvium he's been spouting on stage during the show.
Then again, I didn't actually see him sing this song. It may have been Merv Griffin singing in his stead.
