June 18, 1962 - With the temperature in the nineties today, Perry Como (pictured with Dorothy Collins) celebrated Christmas. The television star exuded Yuletide cheer as he and the guests of his NBC show exchanged season’s greetings. The occasion was the taping of his Christmas telecast, a procedure he instituted last year. The practice eases in-season workloads and makes available guest stars who might be busier in the winter. In other forward-looking programming steps, Mr. Como taped his next Thanksgiving show two weeks ago and his next Easter show last week.
