It's so annoying when people do this. You can pretend like your previous work doesn't exist all you want but everyone else will always remember it. It looks better to accept that your past work might not be the best and be able to joke about it rather then do this whole pretend like you don't even remember it and refuse to talk about it shtick because you think you're so much better now. Also what on earth is embarrassing about See You Again or The Climb?
