Thanks everyone for all your advice.

I wonder if it was partially frozen?  Good point.

I put my temp controller on the fridge to keep the temp from dipping too low.  I will try the shaking and releasing every so often until it tastes better.

I'll let you guys know Saturday if I'm still in good graces with my wife's dad for their party

The beer for the party ended up being really good.  The keg is empty, so it was a success.  All the over-carbonation issues were gone by then.  Thanks to all who passes along tips to me. 
I even had a few people say " Tastes just like Anchor Steam" which made me feel really good, because that was my intention.  I used the recipe from Jamil's book. 

Thanks again for the guidance and tips,
John

Congrats. Gotta love kegging.

I always sample a few days before a party so Ican make sure serving pressures and carbonation are dialed in.

+1.  I've run into this problem before- have a week where I work a lot of hours, there's a bitter cold snap, kegerator in the garage, and I leave the keg pressure as is. Easily enough fixed though.
