Most of what I listen to is rock, especially hard rock. But Olivia Newton-John was a pop singer in a league of her own. She was stunning and incomparable. In my opinion, the only other pop artists that might be considered her peers are Linda Ronstadt and ABBA. Personally, though, Olivia Newton-John was the one I preferred. I didn't like that movie "Grease" that made her so famous. I didn't like all of the syrupy lyrics to some pop songs. But her talent transcended all of that.
She has been sick for a long time. Mentally, I tried to prepare for how this would end. But my efforts seem to have been in vain.
