The Brady Bunch recorded four albums in the early 1970s on Paramount Records: Merry Christmas from The Brady Bunch, Meet The Brady Bunch, The Kids from The Brady Bunch and The Brady Bunch Phonographic Album. There were also various solo singles, and an LP consisting of just Christopher Knight and Maureen McCormick. Barry Williams began work on a solo album, but only six tracks were recorded before the album was cancelled. Along with the Christmas album, It's a Sunshine Day is one of the only Brady Bunch albums currently in print.
In 1974 Paramount sold its record holdings to ABC (the network on which The Brady Bunch had aired). ABC in turn sold their record holdings to MCA in 1979.
"If you have fond memories of watching The Brady Bunch while growing up or if you have all the episodes on tape, there's no escaping it — It's A Sunshine Day: The Best of the Brady Bunch is indispensable" - Stephen Thomas Erlewine for Allmusic.
