It took nearly two years, but we finally found another flaw in Tony Romo’s broadcasting game besides his proclivity to “ooh and ahh” during replay reviews. The Cowboys QB-turned-TV star sings pregame U2 duets with Jim Nantz. “Sunday Bloody Sunday” meet bloody eardrums.

Romo bragged about his song list in a chat this week with New York Post media critic Andrew Marchand. “It gets your voice ready, and it has taken on a life of its own,” Romo said.

The “Star is Born” soundtrack, which features an excellent duet from Lady Gaga and Bradley Cooper, is a newfound favorite of Romo and Nantz’s. But U2 is an old standby, along with Bruce Springsteen and other Gaga selections.

“We go through different songs,” Romo said. “We usually finish with ‘Red Hill Mining’ from U2, and I usually try to make Nantz hit the high note.”

How cute. Marchand reports CBS may air some footage of Romo’s singing during its Super Bowl coverage, which would further cement Sunday’s game as the defining moment of Romo’s broadcasting career. Though Romo has been lavished with praise for his clairvoyance since joining CBS last season, he’s coming off perhaps his best game ever, in which he correctly predicted nearly all of the Patriots’ crucial plays down the stretch.

The performance has become so legendary, Broncos defensive coordinator Wade Phillips said Monday his best hope to stopping Tom Brady is getting an earpiece with Romo in it. Romo’s acumen also got Chiefs defensive coordinator Bob Sutton fired. It made the longtime coach look overmatched.

But then again, it’s hard to imagine anything and sounding worse than a Nantz-Romo rendition of “Beautiful Day.” Maybe CBS should keep these tapes under wraps.
