Factual error: In Los Angeles Madonna complains about her sound not coming out of her headset microphone. She then lists the songs during which this happened. One of the songs she lists is Into The Groove, even though she is not even wearing the headset microphone during this song.
Suggested correction: There are two separate issues regarding the sound. The mic cutting out and the monitors. She states the monitors kept cutting out, and she can't hear herself. She has no inner ear monitors (as they weren't really a thing at that time) - they are basically speakers on the stage, so she can hear herself sing, but if they cut out, she can't hear herself. Also, mic cut out on her regardless if she used a hand mic or used headset. She never specified her headset when talking about Into the Groove.
