How many hyphens should there be in this phrase?
Vietnam war veteran turned performing artist Joe Smith
Your phrase needs either 5 hyphens or a comma. The purpose of the hyphens is to create a single adjective, so that it becomes 'Vietnam-war-veteran-turned-performing-artist Joe Smith'. However, I find that is more elegant, though equally correct, to write about the 'Vietnam war veteran turned performing artist, Joe Smith'.
I'd suggest letting context guide your decision. At the beginning of a sentence, the hyphens make it immediately clear that phrase is a description, though in the case of more than a small handful of words, the hyphens garble the meaning instead of clarifying it.
