Taking a cue from a well-known blogger, I'm checking out the #1 song the day I was born. Actually, there are two songs (I'm guessing an A/B sided record?) that were #1 that day, both by Carole King - "It's Too Late"/"I Feel the Earth Move." These songs seem diametrically opposed - one about the physical joys that can come with a relationship, the other about the ending of a (the same?) relationship - so it's humorous that they'd be on the same record. I seriously doubt this song was playing in my house at the time - my siblings were all young, and my parents didn't listen to Carole King.
