These are some guitar chords and tabs I have done:

The Beatles
Mother Nature's Son (The Beatles)

Paul McCartney
Junk (McCartney / The Beatles Anthology III)

Nirvana
Lake Of Fire (Nirvana Unplugged)
The Man Who Sold The World (Nirvana Unplugged)

Radiohead
Exit Music (For A Film) (OK Computer)
Just (The Bends)
Nice Dream (The Bends)

Super Furry Animals
Nythod Cacwn (Mwng)

Some of them are incomplete.

Also, some are attributed to Nirvana when you might argue they should be attributed to David Bowie or the Meat Puppets. You're just going to have to live with that, I'm afraid.
