I know you're thinking ol' isn't a real word. Well.... it's a variant of the word old and is formed in the same fashion as the long-standing tradition of dropping the final consonant of a word to soften it or simulate a slight drawl. Just like with rockin', rollin' or scrutinizin' grammar until there isn't a drop of joy left in it.
