The Grand Ole Opry stage has seen a lot of surprising performances, but one duet between two of the biggest female voices in country music left a big impression on concertgoers.
During an Opry performance in 2014, Jennifer Nettles covered Dolly Parton's 1980 hit, "9 to 5," with a little help from a surprise guest. About a minute into the song, Carrie Underwood unexpectedly joins Nettles on stage for a completely unrehearsed duet. They kept to the hit's original sound instrumentally, but showcased their own vocal talents with some added runs and improvisation towards the end.
Their version of the popular song, which was nominated for three Grammys and became a cross-genre classic, was obviously a hit with those in the Grand Ole Opry audience.
"Not bad for no rehearsal," Underwood said after the cheering crowd gave an overwhelmingly positive response.
According to Rolling Stone, this wasn't Underwood's first attempt at covering the Dolly Parton hit. In 2010, she began performing the song live after it was voted by fans to be added to her Play On Tour set list.
Underwood is set to return to the Opry stage on June 9, and will also perform as a headliner during this year's CMA Fest nightly concerts at LP Field on June 13.
