G.I. Blues

 is a quest in Fallout: New Vegas.

Quick walkthrough
The King wants to know why Orris is getting lots of money.

The player must hire Orris, and note anything wierd in his activity.

Orris fakes attacks on his clients, for easy fame.

After, The King asks you, to spy a bit on NCR activities.

Optionally, you can talk to Julie Farkas about the aid service there

NCR is doing suspicious activity at the east of Freeside. The locals are rumouring about free water and food. You get inside the building, where they are giving the supplies, and find out, that they're just giving food to NCR residents. (If you did the optional part, it finds out, that they wanted to talk about things with The King, but the commissionary were beaten' up.)If you did the optional part, The King will react positively, to the act, but that doesn't help anything.

Pacer sets up a fight with NCR anyway, and there's no chance of avoiding it, which cause you infamy in the roles of the NCR.
