I had the feeling that they stepped into the vacuum that was created when the Beatles broke up in 1971. It was just a matter of timing.
Remember, a lot of kids were really affected by the vanishing of the Beatles. It had such an “end of an era” feel to it at the time. ELO may have seen it as an opportunity.
Maybe so.
As for this particular song, it is best appreciated along with the entire side of that LP (collectively titled "Concerto For A Rainy Day").
That was also a fun memory like Mr. Blue Sky. I've always regarded ELO and Poco Harem as similar, never a huge fan of either, maybe Beatles chasers but I appreciated what they did. In the same camp of my more favored English bands like Emerson Lake & Palmer, Yes, Genesis, Gentle Giant, and King Crimson, (not in any particular order).
