Question for photographers/photoshoppers

[Dablaze11]

Ok I did a shoot this weekend for a band at a conference they played at and they wanted me to take some band shots, so I did and I was rather pleased with what I got. Only problem is that they want the washed out 70's photograph look. I tried to mess with the saturation and some other things, but never got what I wanted. Does anyone have any advice on what steps I need to take to get this look?

Here is an example of a photo from their website: (yeah i know they had spot lights in this picture, but you get the idea)

I really like photo number 2 But something seems off in both shots. like the lighting on the faces and arms seems whiter then the other side. Im not making sense. Like the three guys on the couch. the one on the far right the lighting looks good But the guys in the middel and far left. seem really bright. I dont know. But over all i like them

Looks like a monolight fired directly at them to camera left. Metered wrong or off the guy on the right end.

Might want to hit up Canon-on-the.net there are some guys on there that do this kind of thing and also on dpchallenge.com
