Here's the whole song, which is the theme from Beethoven's 9th symphony known as the "Ode to Joy." The trick to playing this well is to take your time and follow the music carefully.
It may be more complicated playing with two hands, but the way the music is written makes it easy to tell when the left hand comes in. So in one sense it's actually better like this.
Be patient and see if you can manage it.
