This version is slower than the original in the video below so it's easier to play along with. It's in the key of E. So you can play your E chord for this one. Or you can just play your open low E note along with it (cause it's an E chord, right?), just to learn the rhythm.
This one below is in the key of F. I couldn't find one in A, like we were playing it in class. So find your F note and chord and play it along with the song. It's faster than we played it class but do your best. At least try to get into the rhythm.
