Willie Nelson with Merle Haggard live this long

Time flies by in the blink of an eye
When you get paid for havin' too much fun
Kickin out the foot lights, livin' the night life
Like tomorrow ain't never gonna come
Wouldn't change much of nuthin' about this road we've been runnin'
Full of wild times, wine, women, and a song
But we'd 've taken much better care of ourselves
If we'd 've known we's gonna live this long
Whiskey goes down like cold spring water
Over rocks at the close of the day
When you're flyin like eagles down American highways
Ya lose a lot of friends along the way
If we just keep on movin and rollin' along
Can't look back, we might turn to stone
We'd 've taken much better care of ourselves
If we'd 've known we's gonna live this long
If we'd known we's gonna live this long
We might 'a changed things up a bit
We still would 'a lived out every song
Just maybe not quite as fast as we did
Well were in pretty good shape Will for the shape were in
Well keep rockin along 'till were gone
We'd 've taken much better care of ourselves
If we'd 've known we's gonna live this long
Yeah We would'a taken much better care of ourselves
If we'd 'a known we's gonna live this long
