This song is from Season 5 Episode 21 of Parks and Recreation.
Standard Tuning
Intro -
Once I was a golden swan
A swan of a man
Now that swan s name was andy
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
This is my swan song
Watch me fly
I m gonna find a place where I can be
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)
