Yes, that was the time when all the pretentiousness of FM “art rock”, as opposed to “rock and roll” started. The swan song of the AM radio - Steppenwolf, Strawberry Alarm Clock, Procol Harum, the Troggs. Even the Rolling Stones got confused for a year or so at the time. In the end, all those one hit wonders and bubble gum of the time sound better today than the too-clever-by-half minor key tunes by Cream.
Maybe it wasn't such a bad thing that I didn't have an FM radio at the time.
