The second series, "Rock Follies of '77", was a continuation of the first. Industrial action during May of that year at ITV, the commercial channel that aired the show, caused the last few episodes to be postponed until November. The second series pushed the style further in an experimental direction: where the first series had a lot of dialogue and "offstage" scenes, the second focused more on the music and fantasy sequences, with additional songs and musical interludes used to move the plot forward rather than relying on dialogue as the first had done. More sophisticated video effects were also used.
