The Revival Hour Lyrics Follow

The Brady Bunch Hour is an American variety show featuring skits and songs produced by Sid & Marty Krofft Productions in association with Paramount Television that aired on ABC from November 28, 1976 to May 25, 1977.
The series starred the original cast members of The Brady Bunch, with the exception of Eve Plumb, who was replaced by Geri Reischl (a.k.a. "Fake Jan"). The show began as a 60-minute special titled The Brady Bunch Variety Hour on November 28, 1976. The special garnered high ratings and led to eight additional 60-minute episodes which were produced and aired sporadically under the shortened title The Brady Bunch Hour from January 23 to May 25, 1977.
The show's events are not included or mentioned in the later Brady Bunch revival series and TV reunion movies.
