Although they slept in twin beds throughout the entire run of the series, during the first two seasons of the show, 1951-1953, Ricky and Lucy slept in twin beds that were pushed together on the same box spring. Once little Ricky was born CBS suggested that the beds be pushed apart to diminish the impact of the suggested sexual history of Lucy and Ricky. The only time we see the Ricardo's in two bed pushed together again is when they first move to the bigger apartment into the Mertz' building, however, subsequently after that the beds are pushed apart again.
Lucy! I'm Home!
While Lucy is somewhat consistent in her lack of talent, Ethel at various times is shown to be excellent on the piano, as well as, having a very basic playing ability. In one episode, she plays 'Sweet Sue' and other songs while the group sings, but in various episodes where Lucy is trying to form a band, she is hopelessly inept on the instrument.
In some of the episodes, the guest-star's name(s) are voiced over, by conductor, Wilbur Hatch, in the Opening Credits or Closing Credits.
In reruns of the series, much of the music in the beginning and end of scenes were altered or cut to make way for more commercials. Where possible, many of these musical bridges and cues have been fully restored for the DVD release.
