You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.

auxiliary information: "Sidewalk Talk" is a song by American record producer John "Jellybean" Benitez from his first extended play, Wotupski!?!. It was released on October 21, 1984, by EMI Records as the first single from the EP. The song was written by Madonna and produced by Benitez. They had initially met in 1983 and Benitez worked as a producer on Madonna's self-titled debut album. When he started work on his debut EP, Wotupski!?!, Madonna wrote "Sidewalk Talk" for him. The song features bass and electric guitars, synthesizers, piano as well drums. Lead vocals are sung by singer Catherine Buchanan, and background vocals by Madonna. "Sidewalk Talk" received mixed review from critics, with David Nick Ybarra questioning crediting Buchanan as lead vocalist, instead of a more known singer like Madonna. The song was released initially in 12-inch promotional CD in remix formats to the DJs and the clubs, and reached the top of the Billboard Hot Dance Club Songs chart. It was later released commercially in 7-inch and 12-inch formats, and charted on the Billboard Hot 100. The song also had minor chart placements in the Netherlands, New Zealand as well as the United Kingdom.
