Bob Foster sings Don't Let the Old Man In

I understand that the radiation therapy I will have for throat cancer and lymphoma can cause voice changes, so I recorded this as a sample to compare my voice to when the therapy is complete. The lyrics of this song, which is usually sung by other members of my music group, are also relevant.
Don't let the old man in
I wanna live me some more
Can't leave it up to him
He's knocking on my door
And I knew all of my life
That someday it would end
Get up and go outside
Don't let the old man in
Many moons I have lived
My body's weathered and worn
Ask yourself how would you be
If you didn't know the day you were born
Try to love on your wife
And stay close to your friends
Toast each sundown with wine
Don't let the old man in
Many moons I have lived
My body's weathered and worn
Ask yourself how would you be
If you didn't know the day you were born
When he rides up on his horse
And you feel that cold bitter wind
Look out your window and smile
Don't let the old man in
Look out your window and smile
Don't let the old man in
