Could I ever sing (link to video posted in details)?

I'd love to be able to sing well. I've never had any professional vocal training though. I used to have a good voice when I was young. People used to comment often. I also was in a couple musical/theatrical performance but I never had any main roles. (I was always put into Soprano parts.) I've added a link to a video with me singing Part Of Your World from The Little Mermaid. Keep in mind I've had no training whatsoever and that I know that I've messed up in parts of the song or not came in at the right times. I also know that in some parts my voice does not hit the right notes- I can hear them too, lol. I've never actually sung karaoke before and that was my first attempt. I figured I'd treat this like an audition and whatever the result was on the first try is what I'd show to the Yahoo community. With training do you think I could sing well, or is my singing way too horrendous to even bother? Honest opinions please, I won't get offended. Also, would it take a lot of work to have a voice that was good enough that people would say that I sung well like when I was little? Oh and one last question, what style of music would suit my voice? a href="http://www.youtube.com/watch?v=1tAYkyzPPnM" rel="nofollow"http://www.youtube.com/watch?v=1tAYkyzPP…/a
