Do you think you are just as good a singer as Carrie Underwood, Scotty McCreery, Kelly Clarkson or Jordin Sparks? If so, circle Sept. 10 on your calendar. This is when producers of ABC TV’s American Idol will be holding in-person auditions in Detroit. They are looking for the next singing superstar and want to hear from you. Those who think they have what it takes can submit a full online audition at americanidol.com/audition. American Idol will then hold in-person auditions across the country this summer, including in Detroit. Entrants must be at least 15 years of age. Go to americanidol.com/auditions for details.
