Saturday (Nov. 12) marked the 41st anniversary of the very final Doors concert with Jim Morrison, a drunken mess of a show that took place in New Orleans less than a year before Morrison's untimely demise. Perhaps to commemorate the gig -- or perhaps the timing was totally coincidental -- comedian Jimmy Fallon pulled on his best leather pants and shaggy wig to play dress up as Jim Morrison on Friday's 'Late Night With Jimmy Fallon,' leading a faux Doors band through ... a cover of the 'Reading Rainbow' theme song?

Yes, you read that correctly. Backed by a crack band of unidentified Doors impersonators, Fallon pulled off a dead-on impersonation of Morrison, channeling the sexual energy and charismatic stage presence of the Lizard King as he led "the Doors" through a very impressive rendition of the theme song from the popular children's television series 'Reading Rainbow.'

The Fallon tune starts off with a very Doors-like jazzy groove, picks up steam with the 'Reading Rainbow' lyrics, then veers off into a passage that sounds remarkably like 'The End,' only its lyrics seem to be lifted from the children's books 'Goodnight Moon' and 'The Very Hungry Caterpillar.'

It's not the first time Fallon has tried his hand at mimicking classic rock royalty. Over the last year, he's also channeled Bob Dylan singing the 'Charles in Charge' theme song and pulled off an amazing impersonation of Neil Young taking a stab at pop singer Miley Cyrus' 'Party in the USA.' He's even taken on the guise of Morrison before, turning in a rocking karaoke version of the Doors' 'Roadhouse Blues' at a bar in Nashville.
