With blue lights backing the “Breakaway” musician and her band, which is fittingly called My Band Y’all, Clarkson delivered a strong vocal performance that was met with thunderous applause from her live studio audience.

Clarkson then continued giving her crowd a history lesson on Cole, adding that he’d sue hotels that wouldn’t let him stay the night and also marched on Washington with Dr. King in 1963.

“Before his passing,Martin Luther King Jr.actually wrote him a telegram saying, ‘You have my constant prayers, I will always be indebted to you for your support in this struggle,’ which is an incredible thing I didn’t know as well.”

While this may mark the first time theAmerican Idolwinner has covered a Cole song, it isn’t the first time she’s recommended one to her fans. In her curated holiday playlist oniHeartRadio, Clarkson included a rendition of Cole’s “The Christmas Song” featuring John Legend.

The singer chatted with Khloé Kardashian onTheKelly ClarksonShowabout what it takes to fall out of love back in October, asking her what it meant to “learn to un-love” her exTristan Thompson.

“It’s hard. I think it’s the most ridiculous thing sometimes when something doesn’t work out and you’re in a relationship and you’re so deeply in love — and people are like ‘Oh yeah, why can’t you [move on],'” Clarkson said.

“I think I might always love that person, I don’t know if it goes away.”

Other recent songs performed on Kellyoke includeOlivia Newton-John’s “Hopelessly Devoted to You,” Gin Blossoms’ “Found Out About You,” “I’ll Be Home for Christmas,” andLabelle’s 1974 hit “Lady Marmalade.”
