It's a generational thing: Sonny & Cher when I was a young teen, Moody Blues in my "hippie" phase (preferrred "The Band"). Elton John was an unavoidable presence on the music scene, although I will admit liking "B-B-B-Bennie and the Jets".
Overall, I have a tendency to prefer "oldies" of the '50s and early '60s. In school, we used to frequent a pub twice a week where the DJ played "guess-the-artist-for-a-free-pitcher-of-beer" every half-hour or so. Provided great incentive to hone our skills. Became quite good at it out of necessity. Never could have afforded all that beer otherwise -- only had a part-time minimum wage job while I was in school.
I may not be the "brightest tool in the shed" but I do detect a subtle claim for free beer should we ever meet.
Although I was a few years behind you, I loved the rock and roll of the '70s.
My personal [and maybe only] favorite of Elton John's is "Madman Across the Water." [And yes, he is a madman. But too bad he doesn't stay 'across the water.']
