"Hallelujah I Love Her So" contains the lines "Every morning 'fore the sun comes up / She brings my coffee in my favorite cup," which is fairly similar to "She bought you coffee in a special cup" in "The Feeling's Inside." (The first line of "The Feeling's Inside" is "When you woke up on this cold winter's day," which seems to suggest morning.) Both songs also mention a sort of euphoria related to love - "And if you're feeling very good today" in "The Feeling's Inside," and the titular "Hallelujah I love her so" in "Hallelujah I Love Her So."
I'm slightly more sure of this connection because in this Rod Argent interview, he mentions Ray Charles, but - like most of these - it's still just conjecture.
