My parents went through this too. I wrote a song called "She saw him smile"

She saw him smile He knows her face from somewhere in the past But the smile fades for memories never last She saw him smile

She says "Hello" Buttons up his shirt and combs his hair Although the man she's loved's no longer there She says "Hello"

Remembering when They danced together in the darkened room The blushing bride the nervous, happy groom Remembering then Remebering when

She holds his hand Together they let time pass unrehearsed For time has been and gone and done its worst She holds his hand

She hums their song Hmmm (melody) Hmmm He hums along

And then she leaves He smiles one more time and waves goodbye The picture of her fading fom his eye And then she leaves

And, of course, there's the superb "The Dutchman"
