Can i sing? http://youtu.be/B3BpgzYNeak?

I went to karaoke last weekend and people started cheering and some guy came up to me and asked me if i had considered becomming a singer and that he was an artist promoter who would be willing to help me, but i have never seen myself as a singer. I dont really think im too good or if at all. The link that I have attached has horrible quality but thats the best that I can do with youcam. Please give me your advice. Can I sing?
