Tonight at Maryland’s beautiful Spanish Ballroom (originally built in 1933), the 92 year-old swing dance legend Frankie Manning will do his stuff (www.gottaswing.com for info). It’s interesting to ponder: during a depression, Jim Crow, and a World War, black pop culture gave us Duke Eillington, Ella, and Frankie Manning. Today, with unprecedented opportunity, wealth, and freedom, we get…Jay-Z, P. Diddy and Al Sharpton.
