No Rock And Roll Fun

I AM OVER-SERVED, YOU ARE LOOSENED, HE IS A ROARING DRUNK: What really confuses about Glen Campbell's claims that he wasn't driving drunk, he was just driving "over-served" - because we could have sworn last November he was saying it was the medication that he was on that had lead to the erratic driving and cop-bashing. So does he mean that his local pharmacist had given him more pills than he was expecting? Or is he just trying on new stories like a big ole' stetson to see if any fit well?
