Don't Think Twice, It's Alright [Live version (a)]:

It ain't no use to sit and wonder why, babe
If'n you don't know by now
It ain't no use to sit and wonder why, babe
It don't matter somehow
Well, that rooster crows at the break of dawn
Look out your window and I'll be gone
You're the reason I'm traveling on
Don't think twice, it's alright
