What song? I doubt you need a teacher for the level of playing you're aiming for (and there's nothing wrong with that either...take it as far as you want). However I did have a teacher starting out, and the 1st song I brought to class to learn he regretted to inform me that I wasn't ready for it and needed something more basic at first (that song was Stairway to Heaven of course :D ). So all in all it depends on what song you're wanting to learn?
