I loved Kurt's version. Took a upbeat "teenage love" song from the Sixties and gave it a whole new meaning, full of sadness and pain. And, unfortunately, like Beto, having lost my father to cancer, resonates personally.
I found that episode difficult to watch. Heavy stuff. And, like you and Beto, I have lost both of my parents to cancer. I hate cancer.
But I love Glee!
