YouTube is all about Gene Wilder today, with his "best of" clips wreathed in loving comments. Lots of cancer-community people, including me, are picturing an uproarious reunion between Wilder and his wife, the great comedian Gilda Radner, who died in 1989 of ovarian cancer. I know, because thus far I've outlived that same cancer, that Gene and Gilda were loved by a generation of fans who are now seeing our own third acts right around the corner. Probably there are many people who don't know that, after Gilda's death, Gene took part in establishing Gilda's Clubs, still thriving and still providing a warm gathering place for folks on the cancer ride, along with their families. Another thing even Gene's fans may not remember: He was never funnier than when he was dancing. Take a look.
