Dough Re Mi is the sixteenth episode of Season 3 of The Brady Bunch, and the 65th overall episode of the series. Written by Ben Starr and directed by Allen Baron, it first aired 14 January 1972 on ABC.
Greg writes a song to record with his siblings, but Peter's voice begins to crack.
Greg has written what he figures is a sure-fire hit song, entitled "We Can Make the World a Whole Lot Brighter". His excitement turns to dismay when he doesn't have the $150 needed to rent the recording studio. Peter convinces him that family groups are big, and that with the six of them, they can make the song better, and share in the expenses. With Mike advancing their collective allowances, the kids are able to come up with the money and book the recording time.
As the kids rehearse the song, they notice that something isn't sounding quite right, namely Peter, whose voice is starting to change into manhood. With the recording date a few days away and the money being non-refundable, the kids have to decide if they will record without Peter who contributed throughout the process, record with Peter's cracking voice, or forfeit the $150. Greg writes a new song, "Time to Change", to accommodate the breaking voice.
This episode marks the on-screen singing debut of Marcia and Bobby. Greg's singing debut was in Season 2 episode "Where There's Smoke", while Peter, Jan and Cindy first sang in "The Drummer Boy". Christopher Knight disliked this episode because, of all six Brady kids' actors, he was the only one who didn't like singing.
