I'm looking for a song I heard in recent (Nov 2019) tv commercial. I don't remember what the ad was for or much of the song. Maybe someone here can help me. The ad starts with a car stopped on a road and a child emerges from a field and gets in the car, the song starts with lyrics about a knock, or a smile, or sunshine, something like that. I know it's not much to go on. Thanks in advance for any help. If I see the commercial again, I'll pay better attention and let you know if I figure it out.
