Jeff Tweedy's song "Let's Go Rain" discusses the biblical story of Noah's flood and contemplates the idea of destruction as an act of love. The lyrics suggest that some people believe another flood should occur to wash away the sins of the world. The protagonist reflects on their past as a Christian and the realization that they didn't need to know certain things. They now listen to the sky and interpret rain as a sign, feeling a sense of loneliness when it rains. The idea of building a wooden ark is mentioned, but it is also compared to living on an "ocean of guitars," possibly suggesting a metaphorical escape or solace through music. The song acknowledges that not everyone may be a believer and that some may not have a choice in their beliefs. It also references Scott McCaughey, whose significance may be personal to Jeff Tweedy or symbolize someone who could bring understanding or a different perspective. Overall, "Let's Go Rain" explores themes of faith, doubt, and longing for a higher power or an event that could bring about change or redemption. The song's lyrics evoke a contemplative mood, inviting the listener to interpret and connect with the meaning on a personal level.
