"
and my memory fades
And the crowds don't remember my name
When my hands don't play the strings the same way
Mmm, I know you will still love me the same
Cause honey your soul will never grow old, it's evergreen
And baby, your smile's forever in my mind and memory
And I'm thinking about how
People fall in love in mysterious
This part of the chorus means that when I am old and nobody remembers who I am I know your love for me won't decrease. When he says that you smiles forever in my mind in memory means that he has flashbacks about her smile because it is so beautiful.
