Rock musicians with musical education.

maybe I should learn how to spell ENGLISH....sorry.

Marakanetz actually asked for musicians whom studied music rather than went to university in general.
In terms of general education the list is rather large,Queen being arguably the most qualified band in the history of rock.
A list of musicians who went to Art college is probably longer than those who studied music.
In terms of studying music I can't think of any who weren't mentioned outside the obvious ones Jean Michel Jarre,Rick Wakeman and Elton John,I'm sure keyboard players are the most common.
However it is not a subject I claim to be an expert on.
What was common in England post-war amongst the middle and upper classes was a general education which involved musical studies either part-time and/or in their leisure time.The post-Elvis and then post-Beatles boom were full of such individuals-Procol Harum,Genesis etc.
Nick Drake one of my favourite artists came from such a background but did NOT study music rather English at Cambridge University.

Thanks for great follow-ups! I belive that Keith Emerson also majored in music studies. Believe it or not Rock musicians also played sheet music while studying and training.

The musicians I mentioned w/ the exception of Sting all went to University to study music...bothe Kenny Aronoff and Gregg Bissonette graduated with degrees in music.
