In a weird way, “God Said No” just might be the ultimate Dan Bern song. For a guy who (tongue-in-cheek) sang “I am The Messiah” on the first song on he debut album, writing a whole song about a conversation where he basically asks God to let him alter history isn’t out of the pale.
That said, “God Said No” shows unusual pathos about human weaknesses and God’s understanding as such. The result is a lyric that resonates regardless of your personal belief system. After all, he could be making the exact same requests of The Doctor.
