Looking back at my old school   I think of the things I used to do   And I remember those crazy days gone by   Sometimes I wish I could go back in time, I'd be changing what was then   But after everything's been said and done I'm glad you are my friend      And it's a sweet mystery   That you love me like you do   Oh, it's a sweet mystery to me      Little boy that my mamma knew Became a full grown man   I live my life like you taught me to   You know I try the best I can   And your tender love is so much more than the naked eye could see   When my daddy said I love you boy, you know it meant the world to me      And it's a sweet mystery   That you love me like you do   Oh, it's a sweet mystery to me      I feel you sweet sweet love   I feel your sweet love
