Deep Purple was, and still is, a rock music band. Its members included Mr Gillan, Mr Glover and Mr Paice. In 2005, band members entered into an agreement with HEC Enterprises Limited (HEC) and Deep Purple (Overseas) Limited (DPO). Under that agreement, the parties agreed to form a new company named Purpletuity, to which various copyrights and other assets were to be transferred. In 2015, Mr Gillan, Mr Glover and Mr Paice commenced proceedings against HEC and DPO to enforce that agreement.
