[Willie Nelson]
Time flies by
In the blink of an eye
When you get paid for having too much fun
Kicking out the foot lights
Living the night life
Like tomorrow ain't never going to come
Wouldn't change much of nothing
About this road we've been running
Full of wild times, wild women, and a song
But we'd have taken much better care of ourselves
If we would have known we would live this long

[Merle Haggard]
Whiskey goes down
Like cold, spring water
Over rocks, at the close of the day
When you're flying like Eagles
Down American highways
You lose a lot of friends along the way
But we just keep on moving
And rolling along
Can't look back
We might turn to stone
But we we'd have taken much better care of ourselves
If we would have known we was gonna live this long
[Willie Nelson]
If we'd known we would live this long
We might have changed things up a bit
We still would've lived out every song
Just maybe not quite as fast as we did

[Willie Nelson & Merle Haggard]
But we're in pretty good shape, Will
The shape we're in
We'll keep rocking along, until we're gone
But we'd taken much better care of ourselves
If we'd have known we was gonna live this long
Yeah, we would've taking much better care of ourselves
If we'd have known we was gonna live this long
