I recall Gail Edwards on her website said that It's a Living will likely never be officially released to home video (and why it hasn't already) because all of the assortment of songs that the Sonny character warbled off on the piano in each episode. And it probably would've made the show incomprehensible if you simply tried to edit those segments out.

I imagine that it would be a headache to simply work around the usage of Huey Lewis And The News' "The Heart Of Rock & Roll", "I Write the Songs" by Barry Manilow, Shake Me, Wake Me (When It's Over)" by The Four Tops, or "Dancing in the Street" by Martha and the Vandellas.

I think it's obvious that many shows from the '80s that used a lot of licensed music weren't made with the mind-set that it will on day be on the home video market. They only covered television syndicated repeats. We all know how hard it has become for episodes of WKRP in Cincinnati and The Wonder Years to be released on DVD with the original music intact. This is also why the show Cold Case has never been officially released on home video since it's heavy usage of licensed music went hand in hand with narrative structure of the show.

This post couldn't have had a more perfect timing because all of season 1 is available on Amazon Prime streaming. If you have a prime account, the episodes are free.
