GX1 images all red?

I know stage lighting can easily "confuse" camera metering, but this is very odd. I was shooting a band with my GX1 & Oly 45mm last night and all of a sudden, the images turned all red. Not just showing the red stage lighting, but more or less only recording red, like monochromatic. All the remaining shots of the night came out this way. I didn't really notice it while I was shooting though as I wasn't reviewing the images much after I shot. I had recently attached the LVF2, all though I can't be sure it exactly coincided with the color problem. Below are two examples of pictures taken right after each other showing the switch. These two guys were standing right next to each other, no more than a foot apart. The lighting should not have varied that much. The first one shows the stage lighting, with a strong megenta light, but there is at least other color data. You can see the wood tones in the guitar and the blue in his pants and the background tie-dye. The remaining 17 images of this group are all red like the one below. I was shooting RAW and there is very, very little data from the other color channels. I can upload the RAW images if anyone wants. When I got home and realized what happened, I did take a few other test shots and they came out fine. Also, I was shooting in manual, but with auto white balance. Very strange....

Thanks for the replies!
Sorry for the delay in getting the RAW files uploaded.

Usually I am happy with auto white balance. If the camera doesn't get it right, it is easily corrected in RAW. But in lighting conditions where there is a rather extreme artificial color bias, perhaps setting the white balance manually will give me more room to play with in post processing?

 

turns out there was enough data for a decent black & white conversion...
