I've listened to this song a LOT (one of my favorites) so i apologize for what's going to be an incredibly pedantic review...

You miss a chord change at :44 and 1:10. I noticed it happen a few more times throughout the song. It's a minor I think. VERY IMPORTANT. :P :P

The biggest thing to me though is that the original version is a bit slower. Compare both versions. Stevens takes time to really put emphasis on the words.

Last thing. Get your bro to sing his heart out. Those parts are the most emotionally intense parts of the song! Make the listener cry. >:D

Anyway... beautiful song, great cover.

This played with my emotions a little; the song really relaxed me and made me feel at peace, but I also felt a little sad. However, brilliant singing yet again. You have a beautiful voice and I look forward to hearing more from you.

Pleasant, really.

I pretty much like everything about this: your brother sings very well too.
All with all I don't find anything wrong with this, so I'll just name the positive things:

- Song chosen:
Very good. Cat Stevens is an excellent artist, maybe you should do (yet?) more of him.
- Lyrics/singing
Beautiful. Both you and your brother did an amazing part at this. Just well done.
- Guitar play.
Just as always, excellent. 'Nuff said.

Also, I can't hear anything from your cold, so no worries at that. Job well done; keep it up!

Nice. Mellow, and has great lyrics. Good vocals, good guitar. I don't really know what else to say. I like the concept. I know you said it's a cover, but I never heard the original by cat stevens, so I have nothing to compare it to really. I just really like it.

Good job. :)

I love it :D
You and your brother sound really good together! Nice mellowness with the song choice, nice guitar, and very nice vocals! :"D
Don't know what else to say. Do another one like this? X]
Very very nice. Just sort of instantly calms me down. Except the instantly part. But yeah. My mood just got turned around. :) Thank youuu.
