Two Of Us, by the Beatles.
This song was a highlight of some alternative universe Let It Be anthology, I think? Or does John really make an Everly Brothers reference on the original? Or was Let It Be just the Beatles record I got into last, appropriately enough, having started early in life with mom’s vinyl copies of Meet The Beatles and Rubber Soul? I spent a solid chunk of my teenage years with the back half of Abbey Road on repeat, but feel like I didn’t give Let It Be the time of day until much later in my early twenties. š
