I have been compiling this list of quotes I found throughout the past five or so years about Mick and Keith because I just love them so much and they together, their chemistry, their songwriting and presence, for me have always been the essence of the Stones and why I love them so. Also it makes me sad when some fans still even nowadays think that they hate each other, based on shit they said over 30 years ago, while Mick and Keith themselves are so long over that and everything they, their bandmates, and people who know them are saying, is clearly proving so.
The quotes are taken from magazine/TV/radio interviews, books, websites and documentaries. Unfortunately my toxic trait is to not save links and only copy/paste or type quotes, so I don't have the actual magazine or YT video sources anymore rn

but I added the years and sources as good as I could...feel free to add more quotes you know of or maybe even a source if you remember it
