Accordian Ragtime when I was a kid

I did used to play the accordian (of all instruments) competitively when I was young. I competed internationally and always won first place or grand prize. Always. I never learned to read music,  I sort of put things together using my own hodgepodge method of understanding. And I played a lot of ragtime. Scott Joplin, yay.

I was a kid when did this, however, and unf I didn't keep up wirh it.
