No one says FABULOUS like Christopher Guest from old National Lampoon, SNL, Waiting For Guffman characters. I think Guest appeared with Gilda Radner on Lampoon Radio Hour. Gilda was playing a Helen Reddy type singer trying to get the "I Am A Woman" song right and Guest is catty teaching her how to be a woman.
Click here then listen to song I AM A WOMAN. Another great song on that album is Well-Intentioned Blues written by Guest on the hardship of being a liberal.
