There are no lyrics on Harvey's website. I trust he won't mind us helping Robert out. This is what he sings on 'Brand New Day' (1980):
GIFT OF A BRAND NEW DAY
(Harvey Andrews)

Hey woman, my woman, open your eyes and smile
Hey lovely, my lovely, stay in the warm awhile
Savour the present we've got to open wrapped in a sleepy way
We've got a gift to share together, it's the gift of a brand new day
Gift of a brand new day

Hey woman, my woman, we can walk in the rain
Hey lovely, my lovely, search for the sun again
You can make bread, I can make wine, we'll ask our friends to stay
We've got a gift to share together, it's the gift of a brand new day
Gift of a brand new day

Making music, making love and making harmony
Time goes down, time flows down
The long, long road you share with me

Hey woman, my woman, we can take the baby out
Hey lovely, my lovely, show him what it's all about
Teach him to love the swan and squirrel, the magpie and the jay
We've got a gift to share together, it's the gift of a brand new day
Gift of a brand new day

Making music, making love and making harmony
Time goes down, time flows down
The long, long road you share with me

Repeat 1


For '25 Years on the Road' the last verse is changed to

Hey woman, my woman, now that the kids are grown
Hey lovely, my lovely, there's time to be on our own
These are the best days we've ever had, what a wonderful thing to say
We've got a gift to share together, it's the gift of a brand new day


The only info I have is:
[1972:] To welcome home my wife and baby son, both doing fine. (Notes Harvey Andrews, 'Writer of Songs')
so it would definitely be interesting to hear Harvey himself on the song and the changes he's made.
