My dad met and played some guitar with Roger Miller in the summer of... maybe 1962 or 63? At the time, my dad worked summers at Six Flags over Texas in Arlington. His job was as a wandering guitar-playing musician in the Mexican section of the park. After work he and some other college-age kids would go to a nearby park in Arlington and drink beer and hang out, and he'd take his guitar and play songs.
One time one of his friends brought a stranger along, and introduced him as Roger. None of those kids had ever heard of Roger Miller at that point, but as they were hanging out and my dad was playing music, Roger asked if he could borrow the guitar and he started singing and playing some songs. One of those was an early version of "Dang Me" which he recorded and charted with a peak at #1 within the next year or so.
