Standard Tuning
Intro - Cadd9
Cadd9
Once I was a golden swan
G
A swan of a man
Am
Now that swan's name was andy
F G
And he started a rock'n'roll band
He made incredible nachos
That everybody claimed they loved
And then the band mates dicked him over
With a massive rock'n'roll shove
Cadd9
This is my swan song
G
Watch me fly
Em
I'm gonna find a place where I can be
F Am
the beautiful duckling I always was inside
*wailing* (I think over his cries he's playing G Em F G but it's hard to tell)
