The Dean Martin Show is a TV variety-comedy series that ran from 1965 to 1974 for 264 episodes. It was broadcast by NBC and hosted by Dean Martin. The theme song to the series was his 1964 hit "Everybody Loves Somebody".
Regular segments
Martin sang two solo numbers per show, one a serious ballad. He would join his weekly guests in song medleys, trading lyrics back and forth. Some of these duets were deliberately played for laughs—with Liberace, for example—with special lyrics by Lee Hale to suit the performers.
One recurring segment was based on Martin's club act, in which he would begin to sing a popular song and suddenly insert a gag lyric in an attempt to make his pianist Ken Lane laugh hard enough to break his concentration. The segment usually began with Martin leaping onto Lane's piano; in one episode, the real piano was secretly replaced with a phony one that collapsed when Martin tried to leap onto it.
A knock on the "closet" door occurred each week, with Martin opening the door to reveal an unannounced celebrity guest. Most of the time, Martin did not know who the guest would be, to keep his reactions more spontaneous, according to Hale's book Backstage at the Dean Martin Show.
