Well you can't NOT sing songs because they might upset someone, but this song really made me and others squirm when someone sang it right in the face of another session member who was then undergoing chemotherapy treatment for cancer. Pretty well most of us on the room knew this, but not, apparently the singer. Really horrible during v 6: just saw the guy's face. Thankfully the treatment was successful and the patient is still alive. But I really don't think I ever want to be singing songs about people getting cancer or birth defects
