There is a song from the early 1970s whose lyrics are these

Mary, Mary, when you married me
We didn't have much it was plain to see
But you made a home with 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

There is more, but hopefully the above is enough. I think that the title of the song is "Love kept on". Is that right? Does anyone know who recorded this song?
