I sometimes wish my musical interests had been allowed to thrive. I've pretty well caught up now, and I don't regret the love I have for classical music. For example, the Fauré Requiem that I played last night is one of my favourites, because I sung it when I was a kid. I still prefer it to both Mozart's and Verdi's versions. But there was no opportunity to explore contemporary music when I was growing up. I came to my rock interests through the influence that classical music had on the performers, which is why Jon Lord and Rick Wakeman figure heavily for me. They play familiar instruments like church organs.
So the disco phenomenon left me untouched. I was already struggling to find a source of Pink Floyd and the like.
