The audience for the Cannes screening of Trolls got a special treat when Justin Timberlake and Anna Kendrick, who lend their voices to the animated film, performed an acoustic version of Cyndi Lauper’s classic “True Colors” before the film began. This was the first time the two actually sang together, as they recorded their parts separately for the soundtrack. And Justin strums a lovely guitar accompaniment.
