Great song, "What might have been..." And you did an excellent version. I would pull the harmonies back just a bit to let the lead be "the lead?" I do this with the buses.... LV is "LV" and BV is "BV" And it sits behind LV, maybe spread a little.
One of the best singers on the forum, behind "you know who..." ;-)
It is really good, but could be better.
The other tune I was not familiar with, but it was also very well performed.
