I'm not going to claim, in any way, that Lena Horne's most important work was on Sesame Street, or that it's what she should be most remembered for, or that it's her crowning achievement. But I do remember, even as a little kid, thinking she was the coolest lady ever. So I just thought I'd take a minute and recall that.
(Hat-tip to Stephanie V.W. Lucianovic for the reminder.)
