When he wrote "This Town Ain't Big Enough for Both of Us", Ron could only play it in that key. It was so much work to transpose the song and one of us had to budge, so I made the adjustment to fit in. My voice ain't a "rock" voice. It's not soulful, in the traditional rock way; It's not about "guts". It's untrained, unschooled, I never questioned why I was singing high. It just happened, dictated by the songs. Ron has always written Sparks' lyrics and never transposed them into a rock key for me to sing. He always packed each line with words and I had to sing them as they were.
