#1 - Rich Rat who in life owned a record company that cheated its singers
#2 - Les Leech an agent who "bled" his singers dry
#3 - Vicki Viper a hateful singing star until she loses her voice
That is my guess... ^^; I couldn't never make out Dan's dialogue. Of course as a human, Leech in life would have been a sick, psycho agent who murders his singer clients - hence "bled his singers dry!"
