from the I Love Lucy show to appear on the Comedy Hour were Lucy's mother (who appeared briefly in the "Japan" episode) as Little Ricky's grandma. The first hour had Hedda Hopper in "Lucy Takes a Cruise to Havana". This episode originally ran 75 minutes and Desi had to get permission to air the show intact, cutting into the next show on the network-schedule. After the initial showing on CBS Prime-Time it subsequently was edited down to fit in the 60 minute version that aired during the summers of 1962-1965 and finally 1967. Little Ricky is used more but is still a minor character. Most of his appearances feature him playing the drums, coming and going (examples include "The Celebrity Next Door" and, in several, off to school or some other function); he has no friends, unlike the 6th season of I Love Lucy, where a few are noted ("Little Ricky Gets Stage Fright", "Little Ricky Learns to Play the Drums", several of the Connecticut episodes, etc.); and no plot theme centers on him. Also the Ricardos do not interact with any neighbors in Westport ("The Celebrity Next Door" is the exception, although Bankhead appears in only that episode and features Lucy's only work with the PTA); and the town, a major plot theme in season 6 of I Love Lucy, is hardly mentioned except in passing. Episodes are one hour. Production costs were estimated to be $350,000 per episode. Arnaz had originally proposed to run 10 episodes (one per month) but the high production costs forced Desilu to taper this to 5 episodes each in the 1957–1958, 1958–1959 seasons and 3 in the final season (1959–1960). Arnaz had signed Debbie Reynolds to appear in a season 4 episode to be broadcast in January, 1961 and had been preparing to produce 3 specials for the 1960–1961 season. Ball and Arnaz divorced in May, 1960. After the final Lucy-Desi program the two never worked together onscreen again, although Arnaz executive produced the first 15 of The Lucy Show episodes before leaving Desilu Productions in 1962. Ratings for each episode broadcast (including reruns) during the 1957–58 and 1958–59 seasons were all good. However, by the start of the 1959–60 season, with the habit of viewing Lucy broken up every few months, being broadcast on different nights, as well as the tension revealed between Ball and Arnaz (due to their real-life marriage unraveling),
