Before his performance on Sunday, Smith’s wife Ambershared a loving messageto River on Instagram after their family visited a museum in Chicago.

“Getting back on the road and back into daily life without River has not been easy in the slightest,” she said. “Every single thing reminds me of him, and all I can think about is how he would love exploring and seeing all that we are seeing. I see his name everywhere, I see little red-headed toddlers everywhere. I miss his silly personality and his bright light.”

Amber added, “I look around at everyone else and wonder if anyone is going through something like we are. Dumb little things don’t matter anymore. My family does. My faith does. We’ve got this because God’s got us. Thank you all for your continued support, prayers and love. It really does help us so much. #livelikeriv.”
