Yes, That is the one, David. I have decide to put it away for several years and work on some others. I have a pile that I want to learn and am trying to sort out the easiest ones first.
i would recommend working on that piece a little bit every week. maybe just work out the fingering for the first measure one week and then go back to other tunes. next week, try to work on the second measure, etc. after you've gotten the fingering worked out for every measure, then go back and start working on playing each measure (one a week) in time. then start putting it together.
i think it is all too easy to get caught up in the "all or nothing" approach to practicing. the incremental step-by-step method is much more effective, especially because you can have multiple project tunes going at once.
