Reba McEntire will sing the national anthem at Super Bowl 58 in Las Vegas on Sunday. One popular prop bet is on the length of the national anthem, with the over/under set at 90.5 seconds. In the past, singers like Neil Diamond, Aaron Neville, and Whitney Houston have taken on the task. Reba's previous performances provide some insight, with one clocking in at 1 minute and 19 seconds, and another at 1 minute and 23 seconds. Chris Stapleton went under the set time of 2 minutes and 5 seconds, while Eric Church went over. Luke Bryan hit the under, and Kelly Clarkson matched her set time. Given Reba's history, many believe the under is a safe bet. Country music has been absent from the Super Bowl halftime show for years, and fans are hoping to see that change soon.
