It sounded great. I always enjoy a good barbershop quartet (or however many voices there were). My one critique was it seemed like the energy kind of died towards the end. I liked the punch line of, "[..] to another.. GUY?" After that, it sounded like you were just singing the lyrics. "Do you just sing your part, or sing straight from the heart?" You sang that whole sentence the same way. I'd suggest looking for some way to portray the different emotions that you mention towards the end of the song.
All in all, great job!
