BTW, I've started wondering about the origin of the "walk the walk"/"walk the talk" phrase--does anyone know it?
I've found so far this this film title "Walk the Walk" from the 70s
. No idea if it already uses the phrase in the same way.
The oldest hit in Google Books is the 1968 book Let's Work Together
(about African-Americans), including the sentence "We must cast off the destructive thinking patterns based on oppression that we have permitted to continue, and we must talk the talk and walk the walk of [freedom?]..."
And then there is the somewhat confusing hit
that appears to be from 1900 although the publication date is 1962 (which in other google hits just means that the first
journal volume of the series was printed that year). Anyways, that hit was "He would find it easier, I think, to walk the walk and talk the talk of his infant."
It's used more a couple of times in the 70s, more so in the 80s, and figures rocket in the 90s. (I don't know how much this is due to different numbers of books available for the different decades.)
Sooo... where does the saying really come from? Anyone who knows?
