The Beatles- Let it Be Sheet Music

[TremolO]

Does anyone know where I can find the real way to play it on piano? The version they sell in sheetmusic isn't the way Paul McCartney played it. I have like 3 different versions of it. They are all different. Sometimes it adds a bass note, sometimes it doesn't, sometimes it plays C 1st inversion, sometimes it plays C major with the added octave. I need to know how he played it!  Does anyone know where I can find the real way to play it, even If I have to pay for it. Thank you.
