Well, I'm less enthusiastic about singing over a SMF pre-recorded backing (even if it was made or edited by the singer) than I would be about the performer playing it all "live", by changing chords at the proper time and using fills, intros, endings, and right hand support as needed.

Singing over a SMF edges too close to Karaoke in my opinion, but that's just how I feel...perhaps others would disagree, but I feel a previously-recorded backing takes the performer further out of the performance.

I'm sure both methods have their advantages, but I've always been more impressed with singing "live" while using a style and adding Right Hand parts to embellish.

Nevertheless, you did a bang up job on the vocal and gave the song your own personal stamp.

Nice work, Donny.
