ELO yes :D and Simon & Garfunkel, Dire Straits, Carly Simon, Derek & the Dominoes, Elton John (SO much Elton John - obscure albums on tape in the car) Pink Floyd, Del Amitri, REM, Tears for Fears.
Mike Oldfield's Tubular Bells is an odd one - that was played a lot, but it was a record and at some point we didn't have a record player any more, but it was not popular music that I heard on the radio, so apart from maybe the Exorcist theme, I'd not heard any of the songs for years when I unearthed it on Spotify in about 2015, and it gave me absolute chills to listen to it again. Also nobody has ever heard of it (MN will prove me wrong on this I expect!)
Mostly 70s and 80s music I suppose. The music of their teens and twenties. We also used to listen to local radio, the kind of station that would play a mix of "the 70s, 80s and today". (Incidentally I wonder how long they wait before they change the two "old" decades - 15 years? What do they play now? 90s, 00s and today or are we on 00s/10s already?)
I remember my dad getting a phone call just as Back for Good by Take That came on the radio so he turned it up and put the receiver next to the speaker, thinking it was his girlfriend. It was actually his boss
