Thanks to all for the comments.
evildick - thanks for the thoughtful response. I'm aware of the midi sounding horn, just don't know what to do about it at this point as I have relatively little "midi expertise." However the song needs those lines (IMHO). Right now I think it adds more than it takes away, but could be immensely better with more realistic sounding horns.
samicide - autotune was used to "clean up" a couple of notes in the background harmony, primarily on a couple of sustained notes where the note tended to drift slightly. I also don't consider it the big negative that some people do. Autotune doesn't turn you into a "singer," but it can speed up the recording process. The notes could always be corrected with a "punch in," as almost every singer on earth does. That's an accepted studio technique, yet I fail to see a whole lot of difference, except in the time required.
I also agree with you about the drum fills towards the end. We used a Roland V-Club electronic drum set. The "kit" the drummer chose to use had a decent enough sounding snare and kick, but the tom's were not to my liking.
petelait - I'd like to take credit for the songwriting, but unfortunately copyright laws prevent me from doing that.
theron - by "sharp" on the vocals, you mean too loud? Too in your face? The high harmony part (which I sang) is a bit out of my range. You think that could be the problem?
boydrj - as noted, I agree the horns are a problem. Thanks for listening.
mixmkr - thanks. You could be right about strumming through the entire song. Not sure I have the energy to retrack now, though. But, as you know, sometimes you put these things away on the shelf for awhile, and suddenly a few months later . . .
Kramer - I didn't know the Hootie and the Blowfish had covered this until someone else pointed it out when they heard this version. The original was by a band called Orpheus. I think they were a one hit wonder in the late '60's or early '70's. This song was never a "monster hit," although it has always been one of my favorites.
