During the segment, Welch opened up about her recent vocal cord injury, which caused her to cancel a few of the band's gigs in Europe last weekend. At the time, Welch apologized to her fans and Welch tweeted, "I cannot sing for a week... seriously I felt something snap, it was very frightening."
Welch told Robin Roberts that she lost "about three octaves" in the aftermath of her injury and had to sing in a lower register to get through the show.
