This was your first statement. A 30 second google search revealed very quickly that Manilow did sing the song. It was later that you focused on the word "hit." You have to live with your first statement - which was absurd. You owe the author an apology.
I give up. You apparently are pigheaded and lacking the grace to admit that you were mistaken. I have made my point, presented facts, and you still deny them. This is pointless and I will make no further comment because arguing with fools is pointless.
