Chordify

Pop in a song and these guys will provide you with all the notes you’ll need to practice and perform. Your neighbours will despise you to begin with, but with time and practice they might end up paying to come to your Christmas show. It’s a long shot, but hey. Or, if a drunken opportunity in a pub arises to perform on stage, you’ll know your favourite song off by heart without embarrassing yourself...you’ll most likely still embarrass yourself.
