"And we'll go up, up, up, but I'll fly a little higher," 10-year-old Zachary Le, of Brooklyn Park, sang along with others from his school, from other schools, churches and groups, along with individuals and families.
Le's voice was among thousands who sang "Clouds" in the Mall of America's rotunda Thursday evening. The song was written by Zach Sobiech, an 18-year-old Lakeland teen who died of cancer in May.
Mall officials estimated that 5,000 people circled the rotunda, on four floors, singing along with a video viewed by millions worldwide of Sobiech strumming his guitar and singing "Clouds." In it, he sang his goodbyes while dying of osteosarcoma, a bone cancer that strikes kids.
Thursday, KS95 (94.5 FM) sponsored the "World's Largest 'Clouds' Choir" as part of its radiothon benefiting Children's Cancer Research Fund and Gillette Specialty Children's Care.
From Delano High School to the Twin Cities Gospel Choir, people sang together near two towering tinsel Christmas trees as streamers cascaded down upon them.
"Zach Sobiech, he was a really kind man, and he taught me to live life to the fullest," Le said as he stood in a blue T-shirt nearly reaching his knees and emblazoned with the song's refrain "Up, up, up."
From tiny tots to Sobiech's great-grandmother, people of all ages wore those T-shirts while joining in a rendition of the song that his parents, Laura and Rob Sobiech, said they found full of hope and joy.
"The goal is kind of a pay-it-forward," Rob Sobiech said after the concert. "Zach isn't here anymore, but the community can help with solving children's cancer."
