(Loved the 1970's) I concur, Sir.

An aside: Arthur C. Doyle toured US to sumptuous throngs lecturing on consciousness, the spirit realm and seances in 1920s-ish, iirc. Someone alive in 1970 might have had recollections of that coverage/seen ACD in person and would be in a position to pass on the whiff of ether to an younger generation: hungry for transcendence and shedding of burdens.
