Getting compliments from someone who u feel is beter than you definitely goes a long way. I got a compliment about my drum skills from some professional guys and it made me feel like I was a drummer again, even though I think I suck sometimes.
So, what's the secret bout them LH chords? I know what to play most times, but just can't get there fast enough with my LH. My brain is just stuck on the RH chording channel. I guess I need to just get down to business and practice.
I didn't know that was something I could learn. 
Oh yeah Rue Rue, u can learn anything on the keys. If you can hear it, u should be able to play/learn how to play it.
Our organist learned that Charlie Brown song by listening to it, he said he did it to work on independence. It was pretty cool to watch him learn it.
You definitely do need hand independence to pull that song off correctly. I've been practicing it for a looonngggg time and I still can't play it correctly.
