Eb5         F5            Bb5
Never seen a sun shine like this,  Never seen the moon glow like this
Eb5         F5            Bb5
Never seen the waterfalls like this, Never seen the lights off like this
Eb5         F5            Bb5
Never dug anyone like this,       Never had tasty lips to kiss
Eb5         F5            Bb5
Never had someone to miss         Never wrote a song quite like this

Chorus:
Eb5         F5            Bb5
Fortunate to have you girl I'm so glad you're in my world
Eb5                F5            Bb5
Just as sure as the sky is blue I bless the day that I found you


Eb5      F5            Bb5
Never had room service all night, Never took a trip first class flight
Eb5         F5            Bb5
Never had a love affair so tight  I've never felt a feeling so right
Eb5         F5           Bb5
Never seen a winter so white    Never had words to recite
Eb5         F5            Bb5
Never had a flame to ignite      And I never sang a song with all my might

Same progression throughout....

 Silence child, hope you hear I'm callin' out to your body
Eb5         F5            Bb5
