Thanks Mike, much appreciated. Playing from memory, I don't read music so there are no other choices really. But after working on the vocal version for a dozen takes or so, and then listening to the recording another dozen times, it is not really an accomplishment. I still have a bit of an issue right now getting the very low notes not to "warble", it's not really bad but I notice it. And the "ending", I took 3-4 takes and the last one, turned out that my position to the mic had slightly changed, you can hear a bit of a change in timbre and it is really just the artifact of the sop vs. mic positioning.
Again, thanks for the feedback!
