[Ads-l] Query: Was "on the same page" in use in 1971?

[Cohen, Gerald Leonard]

Was figurative "on the same page" in use in 1971?  Today I received the following query: 
'...But I have an etymological question for you.  In the 2015 film The Stanford Prison Experiment
which I saw at Leach [Theatre] tonight, the expression "on the same page" was used by a group of
colleagues supposedly discussing in real time - 1971 - the experiment.  I never heard the expression used until more recently and associate it with computer-speak.  The expression typical of the era
would be "on the same wavelength" to the best of my recollection.  It struck me as an anachronism.'

Any information would be much appreciated.
