Beginning in 1974 and continuing through the decade, the show would open with different people wishing the Captain "good morning." Many of the openings featured non-celebrities, but some featured stars from TV shows, most of which broadcast over CBS, such as The Bob Newhart Show and One Day at a Time, as well as other characters with a connection to the network, including William Shatner andLeonard Nimoy, dressed as Captain Kirk and Mr. Spock; characters from the Peanuts cartoons; and Fred Rogers from Mister Rogers' Neighborhood. The montage of 'good mornings' would always end with the Captain himself returning the greeting before the opening credits ran.
