“She sang off-key, which, if you’re a really good singer, it is very is difficult,” Potts recalled of Reba McEntire’s appearance on a season 4 episode of ‘Young Sheldon’

Annie Potts is fondly looking back at singing with Reba McEntire on Young Sheldon.

During an appearance with her Young Sheldon costars on The Jennifer Hudson Show on Tuesday, April 16, Potts recalled the season 4 episode “A Pager, a Club and a Cranky Bag of Wrinkles,” in which MeeMaw (Potts) discovers June Ballard (McEntire) has trouble carrying a tune while crooning to Patsy Cline’s poignant song “Crazy” and the pair then show off their off-key vocal stylings by singing “Islands in the Stream” during karaoke.

“The funny thing is they [the show’s writers] wrote [Reba’s] part so that… the idea was that she couldn’t sing,” Potts shared.

“She sang off-key, which, if you’re a really good singer, it is very is difficult. Off-key,” she continued. “But she just like — I don’t know — went up or down a fifth and stayed there. And it was an astonishing thing. A measure of just how good she is, of course.”

Potts, 71, added that the country music superstar was “funny and delightful, sweet and beautiful. All of that.”

In an exclusive interview with PEOPLE at PaleyFest 2024 on April 14, Potts looked back filming the hit CBS comedy, which will come to close on May 16 after seven seasons.

Another favorite episode of Potts remains her first appearance on Young Sheldon in the season 1 episode entitled “Poker, Face and Eggs.” In the episode, MeeMaw babysits the kids after George Sr. (Lance Barber) has a heart attack. When the fiery matriarch goes to the refrigerator for a drink, she pulls out a bottle of rosé and quips, “’What kind of Texan drinks pink wine?’”

“It [the moment] always just tickled me, and I thought that was so defining of her,” Potts explained.

As Young Sheldon wraps filming on the series finale this week, many castmembers are thinking about what little token they might take home from the set to remind them of their time on the show. Raegan Revord wants to take home a tapestry behind her character Missy Cooper’s bed. Revord, 16, would also love to snag a few miniature spoons, which she collects. Barber, 50, meanwhile, has his eye on an acrylic photo cube in George and Mary’s (Zoe Perry) bedroom.

Potts’ planned souvenirs from Young Sheldon aren’t material objects, but they’re no less poignant.

“It’s just incredible that I was walking around the set the other day thinking, oh, that, and then I thought, no, it’s the memories. It’s not an object,” Potts admits. “It’s the feelings that are treasures.”
