I love this song, here's how to play the brilliant 'Proud Mary'! This songs was written by John Fogerty of CCR, and of course the energetic Tina Turner is very famous too.
The chords are the same for either version, so perhaps start by trying to play along with the slower Creedence Clearwater Revival version, then see if you can keep up with the Tina Turner one! Live videos plus tutorial below - all the best with it!
