Xanadu is truly one of the best-worst films of all time. I suggest that for a truly intense evening of bag-on-head viewing you unspool "Sextette" starring an almost embalmed Mae West, followed by "Xanadu" and then, as a finale all to itself, roll out "The Young Girls of Rochefort" by Jacques Demy in all its English-dubbed glory.
