Itsy Bitsy Spider Honestly, it could be something that just sounds vaguely kids music-ish, too. I'm thinking about recording a version of "How Can I Keep From Singing," since hymns are such simply-phrased songs in general. Here's something I'm working on today. Also got a version of "You Are My Sunshine" coming down the line. Still haven't fleshed out the instrumentation, but you get the gist. Short and sweet, a little wiggle room for interpretation. Can be as silly or pretty or direct as you like.
