“In a unique and fantastic case, everything in this verse happened at the same time. I sat down at the piano, played and sang the entire first verse at once! The rest of the song took a while to get right, but I knew where it was going… I was sure of success…”

Also, O'Connell did not miss the opportunity to express admiration for his sister:

“She is possibly the most compelling singer I have ever heard. I never doubted a single word she said. This is such a gift! Her voice is like a Stradivarius violin ... "
