This is Episode #4 of the 1977 Laugh-In revival with no host but a troupe that included Robin Williams, Lennie Shultz, Sergio Aragonés and a lot of folks who, though very talented, never got enough attention later.
This was the Christmas episode and you may not recognize two of the cameo guests. The older lady with the hat is Bella Abzug, a prominent Congresslady who was front and center in the growing women's movement. The gent who acts like an evangelist preacher is Marjoe Gortner, a former evangelist preacher who had a brief acting career and who hosted another series produced by George Schlatter. It was called Speak Up, America and it also starred Jayne Kennedy and Sergio.
There are other interesting folks in this episode and a couple of nice songs written by Billy Barnes…
