Of the many, many Brooklyn Emilys I know, at least two have memorialized the innovative and much-loved Lindy Hop aerialist Frankie Manning. Here's Emily Gordon. The other Emily used Facebook to share a fond memory of dancing with Manning at his 85th birthday party. I believe this is video from that event, held at Roseland.
And here's more of a glimpse of how Frankie liked to celebrate his birthdays. I'm glad I learned about him from the Emilys!
