This is acoustic solo version of the song by Billie Joe Armstrong. Original is by Pinhead Gunpowder, where Armstrong sings and plays the guitar.
Lyrics
Yeah, we say making changes
Starts in the little things you do
“Revolution begins at home“
But for most of us it ends there, too
We’re doing something
We’re making changes
Like changing the brand of crap we buy
We say it makes a difference
But that’s just another lie
