Maybe he moved it because it seemed to be distorted vertically on Yahoo, OK now. Not sure about the title legend incorporating Winston Spencer Churchill as I think he likes to be known as plain Winston Churchill. Don Hunter introduced him as WSC and I think was politely corrected - see photo below where they had a little laugh. Here is the entry on Wikipedia:
Churchill's legal surname is Spencer-Churchill: his ancestor George Spencer changed his name to Spencer-Churchill when he became the 5th Duke of Marlborough, but starting with his great-grandfather, Lord Randolph Churchill, his branch of the Spencer-Churchill family has used the name Churchill only in its public life.
He made an absolutely excellent speech and was the perfect choice. With his physical resemblance, it was as though his grandfather was speaking through him. Particularly poignant since Churchill was acutely aware that the nation's very survival and subsequent progress to eventual victory depended entirely on the ability of the Merchant Navy and allied merchant shipping to maintain the life-line across the hostile seas: "Either the food, supplies, and arms from the New World and from the British Empire arrived across the oceans, or they failed."
