Call me a crank if you like. Not an issue.
Neither is it a likelihood; very persuasively put.
PPS: This song was composed in 1966, while the Beatles met Maharishi
Mahesh Yogi in 1967 so it's unlikely that there are any inputs from
the
Maharishi.
Erwin Schrödinger's 1944 "What is Life?" ( http://
whatislife.stanford.edu/LoCo_files/What-is-Life.pdf ), in which he
successfully predicted than an 'aperiodic crystal' would carry
genetic information, was based on lectures delivered in Dublin in
1943, and he expounded something very similar to your prefatory
explanation in his epilogue: which is a rather long-winded way to say
that, just as one might say that "at least one sheep in scotland is
black on at least one side", it's plausible --even in the UK and even
well before the end of the "Chatterley" ban-- that people other than
the Maharishi might have some influence...
