AMAZING DICK? "Dick is amazing!" I couldn't remember the last time I'd heard anyone say anything along those lines, but last evening an energetic, wide-eyed woman said them to me in Times Square, by the TKTS booth. After some moments of confusion that I'd rather not detail, I realized that this woman wasn't making a pass at me: She was alerting me to the fact that Dick Van Dyke is appearing in Chita Rivera: A Dancer's Life through Thursday evening, January 24.
