Well, I didn't find the words, but you may be interested in how I tried. First I looked at The All-Music Guide and learned that "Twelve" was written by Kirk McLeod, who is a member of Seven Nations, and that it appears on the album "Seven Nations."Then I went to CDNOW and played the sound sample from "Twelve." I couldn't make out all the words, but I heard this much: "Six minutes can't amount to a life/Who would have thought that I could survive?"
Next I tried putting various combinations of those words (allowing for the possibility that I may have misheard a word or two) into Google -- and came up with nothing. Therefore I conclude that the words probably don't exist anywhere on the Internet. If Google can't find it, probably nobody can. I guess you'll have to buy the album and transcribe it yourself, unless you can find somebody else to do it for you. Good luck.
