A funny thing happened on the way to the deluge. When Memphis rap icon Al Kapone and band took the Budweiser Stage at the Beale Street Music Festival about 6 p.m. Friday night, pieces of the sunny sky, as seen through the scattered clouds, were as blue as the polka dots on many of the young women's fashionable yet practical boots. “I feel blessed after all this crazy rain talk. We have defied the forecasts,” said Al Kapone, whose son and fellow performer, Young AJ, was making his third Memphis in May appearance.
