I thought, am I losing my mind or is this one of the best songs I've ever heard in my life? Well, possibly both. But I was thrilled and amazed. And they looked at me for some kind of reaction and I said, I think that's amazing. And perhaps the biggest giveaway is the fact that I immediately asked them if they could play it again. And perhaps the second giveaway is the fact that they were delighted to play it again.
