Here's one I wrote for my own 25th wedding anniversary. Hopefully, this can be added to the database.

ANNIVERSARY SONG
(Mike Campbell)

Long ago when you and I were young dear,
I asked you to be my bride.
You were so pretty, and I was so happy,
To have you walk by my side.
And when I put that ring on your finger,
I promised that we'd never part,
Looking back on the years, I'm telling you dear
These words come from my heart.

(Chorus)
You're the love of my life little darlin',
The only one I'm dreaming of,
You're the sparkle of light that's there to ignight,
All of the stars in the heavens above.
Together we faced all our troubles,
Together we shared all the pain,
We've had lots of fun, we have danced in the sun,
And walked, hand in hand, in the rain.

(Bridge)
Sometimes the waters were troubled,
Sometimes the waters were calm,
Sometimes our boat would leak just a little,
But we kept each other warm.

And through the years we've stayed together
I love you even more today,
And if I had a chance to live it over again,
I wouldn't change one single day.
So happy anniversary darlin',
I hope that you'll always be mine,
We've had a good life as husband and wife,
And I'll love you til the end of time.

(Chorus)

NOTE: My wife Tawmmie and I got married in 1973 and we plan to stay together for all of our lives. M.C.
