I know of no other Marxist analysis of 'Rudolph the Red-nosed Reindeer' and some friends didn't believe that such thing existed.

It's a dead funny and completed unexpected take on it. (He looks at three songs: White Christmas, Rudolf, and Walking in a Winter Wonderland). Who else would have thought to ask what the song says about relations of production at Santa's North Pole factory?

He uses the same sort of critical machinery in a later chapter (with less jokes) to work out why Dylan had such a wide appeal and why his career followed such a weird path. I don't think he gives a complete answer, but he gets nearer than anything else I've read.
