I remember the exact moment when a friend first played me this song earlier this summer. He insisted that he watch my face as I listened to the song – yeah, he is a serious fan. What it really comes down to is the fact that this song is a story told by one of my favorite musicians of all time. In my opinion “Walt Grace” deserves every ounce of your attention. Once you do this, you really gain what the song has to offer and trust me it’s worth it. “Walt Grace’s Submarine Test, January 1967” easily makes itself at home in my top five John Mayer songs of all time.
