Have a Cigar is the third track on Pink Floyd's eighth album of the same name, Wish You Were Here from 1975.
Roy Harper is the singer.

Come in here, dear boy, have a cigar, you're gonna go far
You're gonna fly, you're never gonna die
You're gonna make it if you try, they're gonna love you

Well, I've always had a deep respect and I mean that most sincere
The band is just fantastic, that is really what I think
Oh, by the way, which one's pink?

And did we tell you the name of the game, boy?
We call it riding the gravy train

We're just knocked out, we heard about the sellout
You gotta get an album out, you owe it to the people
We're so happy we can hardly count

Everybody else is just green, have you seen the chart?
It's a hell of a start, it could be made into a monster
If we all pull together as a team

And did we tell you the name of the game, boy?
We call it riding the gravy train
