Slain singer Christina Grimmie was on the minds of some of the artists performing at CMA Music Festival in Nashville this weekend, including Cassadee Pope who, like Grimmie, rose to fame on NBC’s The Voice.

Pope appeared at Nissan Stadium Saturday night (June 11) to perform her hit duet with Chris Young, “Think of You.” Speaking with media backstage beforehand, she said of Grimmie, “I’m performing on her behalf tonight.”
