GREENIN' UP
David Mallett
Cherry Lane Music Pub. Co. Inc. ASCAP

There's an old horse in the pasture, and just like me, he's seen his better days;
But he sniffs the air this mornin' and his eyes take on an old familiar glaze.
He clicks his heels, throws his head, looks right at me like I understood
That it's springtime in the country and the pasture grass is greenin' up real good.

There's a bullfrog in the bog behind my house, and he'll be makin' such a sound
Long late in the afternoon right up 'til the evening sun goes down.
He's happy to be livin' in a world of fiddleheads and rotten wood,
And it's springtime in the country and the pasture grass is greenin' up real good.

It's greenin' up real good, lookin' mighty fine,
Every little seed comin' right on time,
Up across the field, up into the wood,
It's greenin' up real good.

Well, I work all day in the garden. This time of year, there's just too much to do,
But there's a fishin' pole in the corner and it's strung up with a line as fine as dew.
Tomorrow there'll be lots of time to do the million things I know I should,
And it's springtime in the country and the pasture grass is greenin' up real good.

It's greenin' up real good, lookin' mighty fine,
Every little weed, every little vine,
Where the open field gives way to the wood,
It's greenin' up real good.

It's greenin' up real good, lookin' mighty fine,
Every little seed, comin' right on time,
Up across the field, up into the wood,
It's greenin' up real good.
