Host Daryl Somers reunites the gang for the first reunion show. Featuring all your favourite segments, including Red Faces and Wot Cheeze Me Orf, as well as local and international guest acts.

In August 2021, Daryl Somers put out a call for ideas for segments to be filmed for a 50th anniversary special that would air in the future, with some segments already having being shot with key cast members. It was later confirmed that the Seven Network would air the special, titled Hey Hey It's 50 Years, after Channel Nine revealed that it rejected Somers' pitch for the celebration. The one-off 2 hour special aired on 10 October 2021, which is 50 years and one day after the show first debuted. It drew in 1.2 million viewers.

The success of the anniversary special led to Seven commissioning an additional special to air in April 2022.
