While the Orange Bowl crowd did not seem too interested in having Ashlee Simpson kick off the halftime show — she received a lukewarm reception just a couple minutes ago — at least they were treated to live vocals instead of a recording. Too bad that for the first few bars her microphone was turned off. There she was belting it out and no sound was coming out. Then you heard some technical guy saying, “Testing, testing.” It was funny, but not quite as funny as Simpson’s appearance on SNL.
