999's video of old is now down, but you can listen here. Below is my transcription.

For the uninitiated, the references are to outlaw country stars of the 70s: Waylon Jennings, Willie Nelson, Kris Kristopherson (mostly known as a songwriter, but also a talented singer in his own right), Jerry Jeff Walker, and David Allan Coe. In the outro he makes references to, among other songs, Blue Eyes Crying In The Rain, She's a Good Hearted Woman, and George Jones (the woops).

WAYLON'S T-SHIRT

CHORUS
With my Waylon Jennings's t-shirt, Willie Nelson haircut
Kris's lyrics running through my brain
Too much drink and too much smoke
Tell your friends -- ain't no joke
Sometimes I don't know who the hell I am

And I'm tired of chasing other people's rainbows
Sick of someone else's dreams and plans
You know it ain't the money, it's the music
But sometimes I don't know who the hell I am

CHORUS

I've sung those songs about Tennessee and Texas
Like Jerry Jeff and David Allan Coe
Lord, I love that funky country music
But I'm tired of singing songs that I don't know

CHORUS

[Mumbles his way through several of their famous song endings at the end]
