"You Can't Fail Me Know" was co-written and co-produced by Joe Henry (an acclaimed singer/producer who wrote "Don't Tell Me
") and is featured on his album Civilians
. NPR music reviewer Allison L. Stewart compares Henry's version to Loudon Wainwright's: "Formerly a slow, hookless strings-and-guitar ballad, it's now more sparse, more morose (assuming that's possible) and even lovelier."
Henry probably wouldn't agree, considering he is a huge Loudon Wainwright fan; he even calls the singer a hero and a mentor. After the two worked together on "You Can't Fail Me Now" and several other songs for the Knocked Up
soundtrack, Henry could barely keep from gushing about the singer in an LAist
interview: "No he's not just a regular guy. I mean he's a good friend, but I don't hold him in any less high esteem. I think he is one of the most underrated songwriters considering his influence."
