I used to love Eight is Enough and stumbled upon this karaoke version of the theme song – sung by hunk Grant Goodeve who played David. Did you know that Mark Hamill (Luke Skywalker) was originally cast in the role and appears in the pilot? However, after the pilot aired, Hamill got his now legendary role in Star Wars and passed on the role for the series. Now, without further adieu, is the karaoke version of the Season 3 and later theme.
