For someone who loves to wear his Slider T. Rex shirt, I’ve still got some work to do in Marc Bolan’s discography.

Just this past week I saw The T. Rex concert film/documentary/art nonsense piece Born to Boogie and was amazed that no one had suggested it to me earlier. The meat of it is Bolan playing a concert in England, which alone makes it worth a purchase, but the best parts are all the stuff with no audience.

“Tutti Frutti” and “Children of the Revolution” are the product of a jam session between Bolan and his longtime buddies Elton John and Ringo Starr, who is sporting some kind of proto-mullet. It takes place in what looks like a cramped rehearsal space, but the shots are still incredible — almost as much as the jam itself.

Fun fact that I couldn’t find a way to fit in anywhere: Ringo took the cover photo for The Slider. Add that one to the list of famous musicians taking cover photos of other famous albums, which, uh, I think is just The Slider and Will Oldham taking the photo for Slint’s Spiderland.

Click below for one of my other favorite moments from the DVD: Bolan’s tea party medley with a string section and nuns eating hamburgers… It’s a very weird movie.
