Robbie, I've been waiting for you to make a few changes before I posted. In this latest version, I think you may have pulled the vocals down a bit too far because it loses some punch in the finale. Also, on my system, there is more information in the left channel than the right channel. I would have liked to have heard the piano spread out over both channels, or, at least, more bass in the right channel (basses don't always have to be centered). That being said, both your performance and Janet's are right on. You chose a great song to cover, and because it's so epic, many people know this song well. Since your voice and Garfunkle's voice are so different in timbre, I might have gone for a total rearrangement of this song so that you could better "own" it. Nonetheless, you can both be proud of this. The best to both of you!
