Song: Carry It On - Who Sings?

A loooong time ago I had an album {LP, no less} with some songs I really liked. One of the songs on this album was "So Far Away" {also sung by Carole King}, another was "Fixing A Hole" {also sung by the Beatles}. The song I'm particularly interested in {well I'd like the whole album if I could find it} is "Carry It On". Part of the lyrics are:

"Carry it on, carry it on, carry on.
My son, carry it on, carry it on, carry on..."

"I came into this world all alone, my son.
I am here today, but any day I'll be gone.
I will leave this life the way I came, my son..."

"You may choose to use it or reject it, son.
You must do what you will, you have a will, carry on..."

That's about all I can recall of it. I believe it was 1 or 2 guys, possibly brothers{?}, though I'm not sure. NO ONE I've asked has any clue of what I'm talking about so I'm hoping someone here can help me. If I remember right, this was back in 70's/80's when I had the album. I've checked google using different variations of the above and haven't gotten anywhere with it. Anyway, thanks in advance for any help here!
