Here is The B-I-B-L-E for you to play. Try to play it with O/C's before listening to the accompanying midi example. Notice that there is a pickup note at the beginning. You will not play anything with your left hand here. A good general rule is to wait until the first beat of the first full measure to begin playing the O/C.
Remember that you play the octave on beat one, and the chord on beat two. Even though this song uses eighth notes, this does not change our use of the O/C. Only play on the beats. Below is your reference for the above music. In the future, I cannot always provide this extra explanation, with the exception of a few troublesome spots we may come across.
