Overview: Newspaper description #1: Hour-long show devoted to Moscow's famed Moiseyev dancers, with Ray Bloch and his orchestra. Newspaper description #2: Tonight's show should fare considerably better than last week's 10th anniversary program. This one should be a real knock-out with the famous Moiseyev Ballet from Russia as the singular attraction. This will mark the first time that the frenzied folk-dancers have appeared on American TV.
