I also bought the double album "Out of the Blue" but it wasn't until my later teens I started appreciating bands like ELO and Roxy Music.
When Mr Blue Sky was played on the radio, it used to piss me off when the DJ's cut the end part off because it was 'too long' and maybe a little disconnected from the main part of the song.
I can remember very distinctly loving "Livin' thing", in the mid 70's, what a song that was. I still listen to it these days.
Like @cflclosers, I had a several 45's of coloured vinyl by ELO, I remember they did a few.
