Your observations are spot on, thanks. Yep, you are right about the lazy dotted rhythms. Shame on me! Regarding the upward runs at the end, i was influenced by several of the performances of the piece that i enjoyed as a young lad. Never thought about how someone might be irritated by this practice. Certainly some of the "big names" have adopted this as a standard. Guess my name is not big enough to get away with it, lol.
This piece really did need more work before performance, but the radio spot was a promotion for a benefit concert for a local charity, and i learned the polonaise in basically one weekend while attending a church retreat, so there was rather higher than usual anxiety about playing live for the first performance. Perhaps undeserved, i received very positive feedback from the piece (at the benefit concert two days later), so i added it to a program i was playing in September as the closing number, in place of the G-minor Ballade, which had been planned as the finale. This is the complete history of the two recordings.
One thing i learned from the radio experience - i do not want to record in that particular studio again. Didn't care for the piano and less than sparkling quality to the recording. Partially my performance, but i think a good deal also had to do with the setup.
As to the edit from the first submission, you're exactly right - the correction was a from a cut that i took on another piano (as i did not have access to the original instrument in the local Steinway Hall). Although they offered recording/editing courses when i was in school, i never took advantage. Guess i figured there would always be someone else to handle the technical jobs, and i would always just worry about playing. Boy was i wrong!
Will seriously working out/rerecording this piece once i finish up a couple of other projects this fall.
