Old Friend 4 Sale lyrics

The sun set in the west this mornin'
4 I know, I know L.A. is callin'
Bad news, Steve said, and people are talkin'
They say your kingdom is fallin', yeah
They say U lost your fire
When another musician U hired
Little do they know, U wouldn't have passed go
Unless they could take U higher, yeah
The sun set in my heart this afternoon
4 2 friends of mine got stuck in the snow
In Uptown when winter's alarmin', oh
Cocaine becomes charmin'
But U talk about things U don't know 'bout
I know, no matter how pleasant your past was
Green and white return 2 blue
U're happy as long as your last buzz
And then U think U want something new, yeah
The sun, the sun set in my mind this evening
4 someone who said they would die 4 me
Sold some, they sold some more pictures and all my little memories
Chump change is 2 unravel the mystery, ah ha
But life is no fun, life ain't no fun without fantasy
Some things are better left unsaid
And some people are better left untrusted
Maybe, maybe, maybe it'll all make sense when I'm dead
When I'm dead
Old friends 4 sale
Get'em while the gettin' is hot
Watch out, they'll kiss U until they get what U got
And they'll show U the friends that they're not
Old friends 4 sale
