Currently the 5Dimes line on the length of the National Anthem is listed below. I have posted a link to a video of LadyGaga singing the national anthem. If you subtract a second or 2 because she made minor changes to the lyrics that slightly lengthened it, and I think you have to subtract at least a second, but more likely 2, because it will be slicker and better rehearsed for the SB, then she comes in below 132 seconds easy.
The UNDER is the play.
