I've Lived A Lot In My Time lyrics

I've lived a lot in my time (I've lived a lot in my time)
I once had a mansion and lived in my glory
But now I'm down to my last dime;
I had a sweetheart, but I was unfaithful
Oh, I've lived a lot in my time..
Chorus:
I've fought the grim reaper down in the dark valley
I've prayed when the sun would'nt shine;
I've looked through the bars of a cold lonely prison
Oh, I've lived a lot in my time.
--- Instrumental ---
I've been a soldier, and I've been a rambler
Once thought that everything was fine;
I've hoed in the corn fields, I've picked in the cotton
Yes, I've lived a lot in my time.
I've walked with my master, down in the dark valley
And wonderful peace I did find;
Someday I'll journey to Eden's green pastures
Yes, I've lived a lot in my time...
