Just last month, we commemorated 40 years since the world lost the great Louis Armstrong with Satchmo, the fascinating documentary about his life and legacy. But there’s no reason not to also celebrate his birth, which happens to have taken place exactly 110 years ago today. And there’s hardly a better way to do that than by taking delight in one of his most iconic performances, his remarkable rendition of “What a Wonderful World” — with the added joy of serving up a simple reminder of optimism, amidst a particularly difficult year framed by news of every kind of global tragedy, from environmental disaster to large-scale violence to financial and political disillusionment. Sing it, Lou.
