Tarun Shah,
  You're right.  They are not listed in the LA phone book, nor in the
*Hollywood Creative Directory*.  And the receptionist at Michael Mann's
production company has not heard of them, but since Michael Mann
was the producer of "Miami Vice" he will know whom to contact for the
music rights.  The receptionist suggests you fax your request to Michael
Mann and he will respond to you.
