First Song You Learned On Keyboard/Piano

For me it was Mary Had A Little Lamb when I was young, but In The End by Linkin Park was the first real song.

I took piano lessons starting in the 2nd grade. The teacher put us on this book where there was this song with the "first" C, D, and E notes stretching in both directions from middle C. Anyway, it was fun to learn, but the teacher never emphasized the rhythm part and I never understood it until I played drums in high school.
