I LOVE that song ! I've been doing it for 30 years, and I've experimented with all tempos and styles, but you did a bang up job on the vocals !
If you're ever bored .... try slowing it down (WAY down ) and see how you like it as a gushy, romantic ballade. It works that way too!
Everyone, and everything I listen to is my teacher. Every instrument, every voice, every sound in nature ... they are all my private tutor ... 24/7 for free.
