Detroit's Jessica Hernandez and the Deltas appeared on The Late Show with David Letterman Monday night, and Letterman reacted with enthusiasm.
"We have a winner, ladies and gentlemen," Letterman said after the band played "Sorry I Stole Your Man," holding up Hernandez's hand.
"They let us keep Dave's cue cards!" Hernandez says on Facebook.
"I enjoyed that," he added..
So did the 26-year-old Detroiter, who posts on Facebook after the taping:
"Just had the best celebration dinner with our label family, my parents, my bro and my sister-in-law. Now we are off to the hotel to pop the finest bottle . . . New York has to offer and watch ourselves."
She also snaps a mirror-image selfie with a souvenir, shown at right.
Hernandez's family -- a Mexican mother and Cuban father -- owns Armando's restaurant on W. Vernor in southwest Detroit. She grew up in West Bloomfield.
"My parents lived above the restaurant before I was born – I’ve been eating there forever," she tells Alex Miros at CBS Detroit. "The steak fajitas with cheese are really good. Our most popular thing is the Burger Nacho – everyone loves that."
This is her second national splash in three months, following an interview with Scott Simon on NPR's Weekend Edition that told public radio listeners about her "powerful, undeniable voice." Hernandez and the Deltas have performed together since 2008.
