The career odyssey of Sonny and Cher began in a recording studio, led to an abortive attempt at movies and finally to TV, where their comedy-variety show was one of the most popular of the 1970s. At the same time, it shaped Cher as a showbiz and fashion icon and led to the breakup of their marriage in front of all America, and then their reconciliation -- on the tube, at least.
