You're a Grand Old Flag is a patriotic song that pays tribute to the US flag. It was written by George M. Cohen, and it was first used in Barney Goes to School
Lyrics
You're a grand old flag,
You're a high flying flag
And forever in peace may you wave.
You're the emblem of
The land I love.
The home of the free and the brave!
Every heart beats true
'neath the red, white, and blue,
where there's never a boast or brag.
But should auld the acquaintance be forgot,
keep your eye on the grand old flag!
