Paramore’s Hayley Williams paid tribute to Robin Williams at a concert in Denver Tuesday night.

Prior to singing “Last Hope,” Williams said,  “I realized how sad that we had been and how we had been in this place where we weren’t content, we weren’t fulfilled anymore,” she said about the recording of last year’s self-titled album. “It was very scary, it was very depressing. And then this song happened, and sort of a light came on and it was amazing how much I realized I was a part of something — we, the three of us, are part of something…You are part of something. Please know that. This song goes out to Robin Williams.”
