Reviewer Matthew Greenwald at AllMusic.com calls “I Know” “a jazz lullaby.” You know, that’s a pretty apt description of the song.
In fact, here’s Elvis Costello covering it:
At the end of that video, you’ll see Fiona Apple run on stage, embrace Costello and jump up and down. Costello says “Fiona wrote that song. That’s a great song.”
Who am I to argue with Elvis Costello? It is a great song, and a great way to end out sojourn in her musical catalog. Allegedly, she has an album coming out this spring and I can’t wait.
