Tom Smith's "Superman's Sex Life Boogie."

The album and songbook "A Wolfrider's Reflections," based on Elfquest.

Perhaps my own "Emergency Food Supply," based on Excel Saga, though I worked from the anime rather than the manga.

Definitely take a look at Four-Color Love, by Seanan McGuire.

I recall a few X-Men based filks on some of the British tapes (off the top of my head: "Child of Light" and "Rogue" on Phil Allcock's Phil, Philk, and Philched; "Guten Tag" and "Spiral" on Rhodri James' Laughter and Laments). I haven't had any luck finding an online source for lyrics.

If we're including webcomics, there's Rob Balder's "Quest for the Arkentools, Part I" (in the FuMP archive) and my "With Her Mind Bound Up In A Gestalt" based on Erfworld.

One comic based-song I always find compelling is Minstrel's "Elektra's Song"

I believe one of Phil Allcock's earliest compositions was the Redfox song "Requiem"

I'm not sure if you count newspaper comic strips, or just mean comic books, but two "Peanuts" songs jumped into my mind--almeda's "Red-Haired Girl" (a parody of "Brown-Eyed Girl") and lemmozine's Peanuts-based parody of "Vincent/Starry Starry Nights."

In case you were wondering about the provenance of the Redfox comic, here is a wiki reference:
http://en.wikipedia.org/wiki/Redfox_(comic)

A number of Brit Filkfen followed the Redfox comic in the late '80s.

The UK filkers had a run on comic filks in the early/mid 90s:

Me: Shadowcat, "Bright Lady", "Shadowcat", "Nothing In Return" (all on "The Oak The Rowan and the Wild Rose", all X-men filks)
"Cassandra" (on "Shattered Dreams", Judge Anderson from 2000AD
"Someone Else's Dreams" (on Phoenix's "Dancing Flames", X-Men (Rogue))
"Just One Chance", "Halfway There" (on Phoenix's "Dancing Flames", Diamondback from Captain America)
Phil Allcock: "Absent Friends", "Rogue", "Child of Light" (on "Phil, Philk and Filched", ("Absent Friends" also on Phoenix's "Into The Fire"), all X-Men)
"Reqiuem" (on "Phil, Philk and Philched", Valkrie Press's "Redfox")
Chris Bell: "Red Tape and Sealing Wax" (on Rhodri's "Laughter and Laments" and compilation "On Filkley Moor" - Valkyie Press's "Redfox")
Rhodri James: "Guten Tag", "Spiral" (on his solo tape, X-Men (Nightcrawler), latter co written with me, also on Pat Silver's "Windsinger")
Valerie Housden: "Catsblood" (on "Lady In Veils", a Halo Jones (2000AD) filk)
"Beautiful People" (also on "Lady in Veils", X-Men (Jubilee))

That do for now?

Here's a link off Maureen O'Brien's Darn Near All the Filk on the Web site:

I've also got 'Oh, Helen' and 'Time Travel Girl', both based on Narbonic (a web comic).

The 2004 Pegasus had a Comic Book Song category. Already mentioned on this list was Elektra- others were

Arthur Curry by Ookla the Mok (Aquaman)
Catatonia County Rag by Julia Ecklar and Leslie Fish (Elfquest)
Superman's Midlife Crisis by Joe Giacoio
When I Grow Up by Mary Crowell (Roger Rabbit)

Lyrics linked at http://ovff.org/pegasus/year/2004.html.

As well as Minstrel's "Elektra's Song", he has a couple of others:

For Magnus, Wherever I May Find Him (X-Men)

Don't Look Back (Judge Dredd)

Most of the ones I thought of off the top of my head have been mentioned, so I'm left with pluggin' my own. *smiles*

"Let Me In," my Fables-based filk. (I would love to hear more Fables-based filk; that's a big hint to anyone out there ...) Here be the lyrics.

Not a comic book, but a comic strip: "The Beagle," my parody of Simon & Garfunkel's "The Boxer" from the point of view of Charlie Brown: "I am just a young boy with a head shaped like a globe," etc. I replace the "li-li-li" with the Peanuts-adult "wahh-wahh-waah," which makes it audience-participation.

I'm drawing a blank on other songs not mentioned. There are plenty of non-filk Superman songs out there, of course. And I'm certain I've heard a Batman or Elfquest filk sometime, somewhere.

I believe Terence Chua's "Halo Jones" is based on a comic book, but I'm not 100% certain.

One of my favorite has the phrase "Mutant heaven has revolving doors" (is that the title?) and it's a filk of "Heaven is a Place on Earth" performed (though unlikely written) by Belinda Carlisle. I'm sure the British filkers will be able to provide the correct title and lyric attribution.

Thanks Mike! I certainly caught the Transept performance. Watching Phil spin around was the best!

For older comics, how about the original Captain Marvel? You can find THE BIG RED CHEESE here:

For my own works there's my Batman filk THE DARK KNIGHT, (though it has a direct reference to the BATMAN movie rather than the comics, I'd guess it would still be OK). I'll have to type out the lyrics later if you're still in need of more songs, I've got guests coming shortly.

Hello! Like your new journal layout.

I don't know if Luke Ski is considered filk, but i know he's played with Ookla before. He's got a rap about Peter Parker and an original song House Party at Arkham Asylum among others.

hope you are having a wonderful weekend :)

sodyera has several original Batman songs that she performs in filk circles.

Superhero Songs lists references for comics references in song. It's broken down by character. It's not limited to filk though, since it includes more mainstream references as well.
