EDIT 2: Listen, I'm not forcing ANY of you to look at my post. If you don't care about any of this, then you don't have to go out of your way to comment - you can simply scroll past.
EDIT 3: Also, I'm not looking to argue with people - I'm totally open to discussion and debate as long as it's done without redditor's penchant for insults and needless conflict.
As a preface: I'm not trying to slander anyone with this post. Simply put, I'm passionate about Radiohead and would like to attempt to address some of the misinformation I've seen on this subreddit, mostly concerning Ed since that's where I've seen the most. The majority of what I write is established fact, though some of this post is speculation (speculation with good cause and facts, that is).
Part 1:
-Ed did not write the Street Spirit riff, it was written by Thom and performed by Ed in the studio version. Ed confirmed this himself.
-Ed mentions in this same interview that it's the only part he's played on a studio recording that was written by another member (from what he can remember). This is absolutely true for the studio versions of their songs: members play what they write. However, when it comes to live performances, it's not as true. Ed in particular has plenty of live parts that were written (and likely played) by other members on the studio versions, a few of which I'm going to mention.
-Some people suggest that since Ed performs it in the live versions, he must have written the No Surprises riff. There's not a whole lot of evidence to support this. Early versions of the riff appear on Thom's minidisc demo, making me think that it was Thom who wrote and likely performed it (I'm not denying that Ed could've altered it into its final state). There's also an excerpt on the citizen insane website in which Thom details showing the band No Surprises on his acoustic guitar https://citizeninsane.eu/music/okc/nosurprises.html.
-Again, if we're going off of Thom's minidisc demos, Ed's live part in Climbing Up the Walls was written and likely performed by Thom https://www.youtube.com/watch?v=4d25dO-2Rqs&list=RD4d25dO-2Rqs&start_radio=1.
-Same thing with Let Down: While Ed plays it in the live version, it's evident from Thom's demo that Thom wrote the core riff/chord progression (Jonny wrote the 5/4 polyrhythm).
-Ed did write the main riffs for Lull, Meeting in the Aisle, and Man of War (as well as the bridge for Let Down). Can't find the OG interviews in which Ed said he wrote Meeting in the Aisle and Man of War but I remember reading them pretty distinctly.
Part 2:
-There is still zero tangible evidence to suggest that Ed wrote the Go to Sleep riff, besides him playing it in most of the life versions. For something so regularly stated as a fact, you'd think there'd be much more proof but I digress.
-Dollars and Cents originated from Colin, not Ed. Also, according to Ed's diaries (you can read them on the citizen insane website), the guitar on this track comes from Thom https://citizeninsane.eu/music/amnesiac/dollarsandcents.html.
-Neither Ed or Colin wrote Myxomatosis, that was Thom. Thom made the first demo in 2001 or 2002 (and handed it off to Cristian Vogel for Remyxomatosis on the Com Lag EP).
-Ed did not write the titular Weird Fishes arpeggio, that was Jonny. I've also seen people say that Ed wrote the "rain down" section of Paranoid Android - again, that was Jonny, not Ed. I don't think I'll link a source here being that these tidbits are pretty common knowledge amongst Radiohead fans.
-While Ed sings most of the live backing vocals, nearly all the studio vocal harmonies are composed and performed by Thom. In this vein, all of the lyrics are written and sourced by Thom (including songs that originated from Jonny like A Wolf at the Door or The Tourist) minus a few lines from Colin on Trans-Atlantic Drawl.
Part 3:
-This is me being petty, but I got into an argument on my alt account over this point (before my comments were promptly deleted by a moderator), so I'll repeat the facts again: Thom does play bass on the studio version of Kid A. Colin was not available that day. Also, that track was basically all Jonny, including the vocal melody. See the above link again for a source on that.
-I've seen this sentiment floating around, so I might as well address it: "The Smile is simply Radiohead without Ed, Colin, and Phil." This is false as it relies on the presupposition that Thom/Jonny write and edit for both bands with the same approach. Jonny himself stated that The Smile was an outlet for a quicker and less deliberate creative process without all the baggage and expectations that come with being in Radiohead.
Now, I want to make something abundantly clear: I love Ed. The band wouldn't be the same without him (or Colin, Phil, and Nigel for that matter) and his many textural contributions (lots of The Bends, Airbag, Lucky, How to Disappear, Treefingers, Idioteque, Bloom, Separator, Ful Stop, etc.), but that doesn't really excuse this sub's incessant desire to both falsely attribute Thom and Jonny's musical contributions to him and to falsely claim that live parts always translate to studio parts.
