Grateful Dead cover - Wharf Rat

I can't seem to finish a song without at least one mess-up. I'd like to say that in my prep to leave the country, I've spent almost no time practicing the guitar, and that's why. But the fact is, I've always been mistake-prone; playing for myself in my room, I really don't try to perfect my play since I'm not trying to impress anyone. Maybe I should start trying? And believe it or not, my voice has still not recovered. I'm not what I consider to be a "natural" singer, so when I don't get to practice often (as was the case when I was sick), I need a good three to four weeks to feel that I'm able to hit notes correctly again. It's been about 1 week since I feel I've more or less recovered from my sickness...whatever the heck it was! Anyway, as always, thanks for watching. And I'm really enjoying the feedback and encouragement from people. Thanks. :)
