I really don't know, but I could dive into the vaults of my music books and find the first music book I owned. I got it in school at around 7 when I learned to play recorder. It was most probably something children's songs like Kuckuck ruft's aus dem Wald "or "Summ, summ, summ, Bienchen summ herum". Songs like these were also the first when I started with accordion two or three years later.

When I pickud up the guitar I raised the strings to play it like a Hawaiian Steel Guitar, the first song was "I Feel Better All Over" in the version of Johnny Cash

On regular guitar, I don't know which songs I played first, but the two first ones that I really mastered were "Steel Guitar Rag" and "Walk Don't Run" in the Ventures version. Also I learned one (!) song fingerpicking from a Stefan Grossman Album "Shake That Thing!

On pedal steel guitar the songs were "Steel Guitar Rag" that I already knew on guitar and "Bud's Bounce". (I don't play pedal steel anymore, but I still have it...) Meanwhil I try to re-learn Bud's Bounce on guitar more or less in the arrangement for pedal steel guitar.
