Once in a while will you try to give one little thought to me
Though someone else maybe nearer your heart
Once in a while will you dream of the moments I shared with you,
Moments before we two drifted apart.
In love's smoldering ember, one spark may remain,
If love still can remember the spark may burn again.
I know that I'll be contented with yesterday's memory,
Knowing you think of me once in a while.
