This 1963 season opener ( the last on CBS ) was shot on videotape and transferred to film.
By the mid 1950s Jack's shows were usually filmed to begin with,
but this orginated from CBS Television City in Hollywood -- where they had
done live shows back in the early seasons, as those alternated with
filmed episodes beginning with Season 4.
This is from " The Jack Benny Program Lost Episodes " DVD collection that came
out back in June, which I don't own.......yet!
