Working For the Weekend (Instructional Keyboard Cover)

This is my cover of Loverboy's "Working For the Weekend". I'm pretty sure the whole main riff is, normally, doubled with both hands. But, I think it sounds better with only the right handf for part of it. I was lucky enough to find a transcription for the crazy keyboard part in the middle of the song (which is very difficult to isolate when listening to the song). The "oboe-sounding" part in the middle of the song is very subtle and difficult to hear, but I strive to make songs sound as close as possible to the original. When the main riff goes up an octave toward the end of the song, I'm pretty sure there is some overdubbing, as it would take three hands to reproduce, accurately. I just have the right hand ascend an octave, instead of having both hands ascend. Again, I think this just sounds closer to the original.
