Can anybody tell me which song is this?

Hai. I heard this song on the radio once and i linked it very much. I did an internet search for this song very much but in vain. The lirics go as this "...It's a damn cold night. Won't nobody come take me home? I don't know who you are but i am with you...." These come somewhere in the middle. Could anybody tell me which song is this and where on the internet can i get it's free download? Thanks.
