Love kept on? Who and when?

Here are the lyrics from a song that I think is from the late 1960s. I can't find who recorded it -- Michael Graham?
Is it out there in cyberspace somewhere?

Mary, Mary when you married me
We didn't have much, it was plain to see
But you made a home of the things we had
Filled it with love when the times were bad

Never once did you complain
Or say you were ashamed
Of two chairs, a bed, a table, and a baby
And love kept on and on yeah
It kept on growing stronger
And love kept on

Mary, Mary you were always there
Easing my troubles with your loving care
Remember the times all we had was pride
Always knew you were by my side

Never once did you complain
Or say you were ashamed
Of two chairs, a bed, a table, and a baby
And love kept on and on yeah
It kept on growing stronger
And love kept on

Mary, Mary from the patio
We can admire our new bungalo
But God up in heaven he gave us more
Only job was to thank Him for

Never once did you complain
Or say you were ashamed
Of two chairs, a bed, a table, and a baby
And love kept on and on yeah
It kept on growing stronger
And love kept on

Is song really 60s or just felt 60s
elsewise this song probably come into question too
