Whatever you do, MissAnthropist, just be sure you're hitting with the right and left sticks in an even tempo. Don't dot the notes, and don't accent them. Just even mum-my dad-dy mum-my dad-dy mum-my dad-dy... Then speed up until you can just play it, and slow down again.
It gets better, then it gets worse, then better again. But it takes another two decades to sort itself out. I hope that helps... but I know it doesn't. Sorry. Come sit with me on The Porch a while. Later we can get a sitter and go to The Verbal Arms. ;-)
