Even during these dark times, Billie Eilish and Finneas still want to make sure that they're brightening their fans' days, as the showed during Saturday night's (April 18) One World: Together at Home.Seated in a brightly lit room with Finneas playing the piano, Eilish performed a moving cover of Bobby Hebb's 1966 song "Sunny." As Eilish sang out the loving lyrics, her brother managed to throw in the four-note James Bond motif as a tip of the hat to their last song together, "No Time To Die."At the song's end, Eilish thanked medical workers everywhere for their continued work. "Sending our love to you," she said.
