I'm a bit similar, Don. I tried music lessons a long time ago but quit early on - kept getting ahead of myself. Fast ears an' all that. While I don't have perfect pitch, I'm strong on relative pitch, which I think is the nub of being able to play, not virtuoso in the grand sense, but for everyday, all-purpose gigging it works just fine. And I sing well and on pitch. That's pitch relativity kicking in again. For who knows what reason, I was just born with this stuff and I think I've used the gift well.
Think of all the pleasure you've brought to people over the years. That's a nice contribution to have made to the world. And let's hope we can continue to do that for as long as possible.
