Boy, that "angel" line is a hard one to make out. I can't agree with the "Bill" interpretation. I saw one that had it "an angel so mission-filled," which sounds pretty close to what I hear. Richard Matteson has it "An angel procession fills" - don't know if I buy that one, either.
The best interpretation of the Carter recording I can muster is, "garble, angel, garble, garble, garble." But if you really want to know what I think it is, I'll vote for "an angel so vision-filled."
