ShiSho - which is sort of a Kids and Dad band for the pre-Smoosh crowd - cover Sufjan Steven's "Get Behind Me Santa" as a fun revenge for what looks like Sufjan stealing their title. It's what you would expect - nothing great but kinda funny and fun - cute, but of course. Great mash-up photo for the cover of their single, too.
You can download the cover and more on their page.
More than Milk was the first blog -- I think -- to cover this and they're also offering the songs for download (including the Sufjan song) - the links are effed up right now but I'm sure he'll fix 'em.
