I'm actually thinking about getting Jackson a little guitar for his 3rd birthday. Ever since making that Dialtone video of him, he asks to play John's guitar incessantly. I didn't think that someone his age could really pick up an instrument, but when we asked folks how old they were when they started playing on a Facebook post recently, I was really surprised to hear a couple of people say as young as 4/5. Let's just hope it's the guitar and not drums.
