Round about 1979, on a family visit, my cousin Chris couldn’t wait to play “the best song he ever heard” for my older sister and me. The song was “Rapper’s Delight.” My sister and I, having just spent a summer singing along to “You Picked a Fine Time to Leave Me Lucille,” couldn’t make heads or tails of it. Who knew a white kid from Connecticut would turn out to be so ahead of the musical curve?
